What guests think

Reviews of Radisson Blu Hotel, Istanbul Sisli highlight friendly, helpful staff, clean and comfortable rooms, and a convenient location near Şişli Metro and shopping, with many guests praising the breakfast, executive lounge, pools, and overall amenities.

Repeated downsides include malfunctioning elevator key cards, air conditioning problems, and some rooms without outside windows or with street noise. There is also mixed feedback on spa and hammam cleanliness, occasional cold pool or jacuzzi temperatures, slow or weak Wi-Fi, and service lapses in a minority of stays. Overall, expect a well-located, full-service stay with modern comforts and a few maintenance quirks.

I stayed at the Raddisson blu hotel in SISLI Istanbul for one week in a executive room, which you get use of the club lounge which was a great choice, you get free soft drinks, coffee and cakes from 12-30 to 17-30 then from 17-30 to 19-30 you get free food consisting of canapés and also good quality meals you can dish up, also wine, beers and more soft drinks and coffees, the staff at the hotel were very friendly and helpful for your needs, there is an outside swimming pool which was great, as there are not to many hotels in this area of Istanbul with this facility, the bedrooms are of good quality and the cleaning of rooms was very good, so a great choice of hotel to stay in 👍

Odamızdaki saç kurutma makinesi eski ve sorunluydu. Talebimizle kısa sürede yenisiyle değiştiler. Koltuk yatak çok konforsuzdu. Yetişkin için sağlıklı olmayacaktır. Bel-boyun ağrılarına neden olabilir. Daha çok küçük çocuklara hitap ediyor. Kahvaltıdaki peynirleri beğenmedim. Çok fabrikasyon ve sıradan geldi. O otele ordaki hiçbir peynir kalite olarak uymuyor. Otelde konaklayanlar için otopark ücreti sembolik olmalıydı. 500 TL bir gece için çok fazla bence.

Comfortable bed, quiet room, great for food options - breakfast buffet, tea and cookies, and the «\xa0appetizers\xa0» in the lounge were enough for dinner! Also, wine and beer were provided in the lounge. Great fitness facilities, including indoor and outdoor pool. And don’t miss the hammam experience!

Le personnel est adorable, les agents à la réception sont très dévoués et gracieux. Cependant les produits servis au petit-déjeuner sont simples, pas vraiment de qualité, de même que au Lounge pour le chambre exécutive. Pour un hôtel 5 étoiles, le spa laisse à désirer… le hamam sent l’urine, il n’y a pas suffisamment de services de toilettes, ni foutahs

Super séjour au sein du Radisson blue Sisli. Le personnel est adorable et prêt à rendre service. Les petits déjeuners sont extra et varié pour tous les goûts. La chambre exécutive est spacieuse, très confortable, avec des bouteilles d’eau chaque jour. Nous avions accès au salon VIP, un espace pour prendre des goûters, un extra pas négligeable (mon seul regret est que nous en avons profitez que le dernier jour, par oubli..) La piscine est grande (nous en avons pas trop profité car beaucoup de vent sur la semaine où nous étions la) La salle de sport était convenable et pratique, avec des cours le soir. À deux pas de la station de métro Sisli qui nous emmène partout dans Istanbul, sinon des taxis sont à dispositions devant l’hôtel. En bref, réservez votre séjour ici !

We booked two rooms. Both rooms had a lobby view which was really bad, don’t have a window to look outside. No privacy, noise from lobby all day because of the interior window. I woke up one day because of the alarm from other room!! The AC was too hot which made us uncomfortable. The card system inside elevators are really bad, we had to insert the card and choose our floor number, but many times it wasn’t working and we go up and down trying to make it work. Never coming back.

Excellent staff. Breakfast and food was great. Unfortunately, this was the second time we’ve stayed here and the room we received had air conditioning that did not work properly. Management tried to fix it multiple times and finally asked us to open our window. Yes, a 5-Star hotel and we had to let the exhaust fumes and road noise in all night. It was a miserable experience with a toddler, but we couldn’t leave as all surrounding hotels were fully booked with a large conference. Radisson was also unable to offer us another room.

A hotel not worthy of Radisson's reputation. Check-in staff bordering on the aggressive, who couldn't find my reservation and accused me of "going to the wrong hotel", only to acknowledge their mistake without apologizing. A room where the air-conditioning didn't work and was never repaired (between 25-26 degrees in the room). A window (on the 1st floor) that opened completely, posing serious safety concerns. Extremely poor wifi, making it impossible to surf the web or use any applications. An exorbitant price for almost no service. Hotel be avoided at all costs, as this establishment is an affront to legendary Turkish hospitality.

Dårlig indeklima på værelset, ikke mulighed for at åbne vindue - prisen taget i betragtning burde standart være højere.. også til morgen buffet hvor der var mangel på plads og mangel på opfølgning , personale meget larmende. Også prisen taget i betragtning. Fitness faciliteter Ok👍

Everything about this hotel was truly excellent. From the moment I arrived, the staff were welcoming—he even checked me in early because my flight is an early morning flight so I arrived at the hotel ~ 9AM. The room was clean, the housekeeping staff was always cheerful with her good morning, the restaurant servers were attentive, and the front desk team was outstanding. In fact, every staff member I interacted with was friendly, polite, and professional.

⸻ Samlet vurdering: God beliggenhed og fin morgenmad – men flere skuffelser under opholdet. Positivt: Hotellet var rent og pænt med en rigtig god placering, tæt på det meste. Morgenmaden var lækker og havde et fint udvalg. Værelserne med vinduer mod gaden var lyse og behagelige. Negativt: Ved check-in blev vi bedt om at betale 100 euro i depositum pr. værelse, hvilket ikke var oplyst på hotellets hjemmeside. Værelser med vinduer mod hotellets indre gård var mørke og mindre indbydende. Servicen på værelserne var mangelfuld – der var kun to små kaffekopper og to vandglas, og intet bestik. Nøglekortene virkede ofte ikke i hverken døre eller elevatorer, som i øvrigt er den eneste adgang, da der ikke er trapper til gæster. Personalet virkede uvenlige og ikke særligt imødekommende. Der manglede også praktisk information om hotellet under opholdet.
