This was my favorite Airbnb when I travelled to Spain this year. The location is very ideal, a 2-3 min walk to Gran Via. However, the 5 flights of stairs are no joke, so keep that in mind if you have a lot of luggage.
The actual Airbnb is perfect for a couple and is well equipped with everything you would need. The bed is comfortable, the TV has Chromecast to log in with Netflix or Disney Plus, and the kitchen has a good set of wares and basic spices. The shower maintains a good pressure and water temperature throughout your shower. (Much better than some of the other Airbnbs I’ve stayed in the past.)
All in all, if you can manage the stairs, this Airbnb is well worth it.
