This place was amazing, and Rosa is simply the best host you could hope for! It looks exactly like the photos; the bed is firm and comfy, the bathroom shower pressure is incredible. You have your side of the apartment and Rosa has hers, so it is very private at night (and right by the door so you won't wake her coming in late.) Rosa was basically my expert concierge as well. She helped me immensely with dealing with a delayed bag and arranging a taxi to go to the airport. The location is spectacular for anybody interested in the museums (Prado, Reina Sofia is 3 minutes away at the end of the street!, and the Thyssen are all easy, 10-mins or less walking distance) and it's a great, real people neighborhood. There's a supermarket and mercado on the block, so you can easily grab supplies for breakfast/lunch and have a great meal at home. Rosa very kindly provided a pile of starter food so that I had something to eat and a glass of wine when I arrived. Only possible issue to know about is that the #1 subway line that stops right by the house IS NOT RUNNING until November 2016, so until then, you'll have to walk to Sol or other stops. Really, I couldn't say enough about it! I would come back here in a second.
