(1,000 reviews) This is our second stay at the Warwick since 2022\. For our purposes, it served well. Very central to everything, walkable to many attractions. However, we have noticed how dirty the sidewalks are in the area, mainly of dog poop, which is quite gross. You feel the need to boil your shoes when you get home. But that is of no fault of the Warwick. The restaurant and bar are great. The tapas sized plates are ideal for a snack, or getting a bunch to satisfy a dinner portion. Very friendly staff at all hours of the day! Good times overall!
