Minimal provisions for breakfast. Unless you intend to pack on carbs first thing in the morning. Only protein was boiled eggs, cream cheese (for the bagels), and sugared yogurt.

The location is in a bit of a sketchy area and the outside areas are a bit dated, but the rooms are very nice and well maintained!

It’s basically under a freeway, they were understaffed, hours for breakfast were brief, it was not welcoming, and when we got back to the room at the end of the day our door was left open by housekeeping, and our key was demagnetized. The beds were comfortable though.
