AC Hotel San Sebastián de los Reyes by Marriott

Facilities are basic, with a small gym reported. Parking is available for a fee, though several guests found easy street parking nearby.

Cleanliness earns strong feedback across reviews, with rooms described as very clean or impeccable. A few isolated issues were noted, including a ceiling mark in one room.

Rooms are comfortable or well equipped for many, and some are spacious. However, multiple reviews note thin walls or nighttime noise, occasional small rooms, an inferior extra bed in a triple, and unreliable Wi‑Fi on a lower floor.

Service is widely described as friendly, helpful, and efficient, with smooth check‑ins and accommodating staff; however, one review mentions less pleasant interactions.

Location suits airport access and nearby shopping, but it is outside central Madrid; some found walking limited, while trains or driving offer reasonable access to the city.

Breakfast is often praised for quality and variety, though some find the hot choices basic. Evening and weekend dining are limited or unavailable, with no on‑site restaurant beyond breakfast and occasional gaps in room service.
