Location, location, location!! Great area easily accessible to all of Madrid by Metro, bike, taxi, and walking. Paid parking is next door although I didn't use. There are so many restaurants and bars in the area with short walk to Sol Plaza. The apartment was comfortable with great views in a building that has several other Airbnb apartments. The street was somewhat busy but when the windows are closed it is quiet. My only complaint was that the towels smelled like mildew (hopefully hosts will replace with new). I couldn't find the iron but there is an ironing board (I didn't ask the host as ditched the effort to iron some shorts). Apartment is on 5th level but there is a small lift available after going up one flight of stairs. Hosts were very responsive to requests.
Bed - 3/5 thin mattress but ok, old sheets
Bath - 3/5 some mildew in the shower grout, Hot water was very good
Hair Dryer - 5/5, full size/power
Views - 4/5, great street view on small square and if you look around to the right you can catch a glimpse of the sunsets
Safety - 4/5, good security locks, as always be aware of surroundings when entering or exiting building
Good price for great location!
