We loved it. Perfect size for two people. Bigger than I expected it to be. Very clean and neat. 4th floor, so very good view onto the plaza. It has all the amenities that you would expect (Nespresso coffee maker, microwave, tea kettle, refrigerator, etc). You could cook if you wanted to, but we didn't bother. The plaza is lively at all times of day (which is a positive, not a negative). The flat itself was quiet. We felt safe everywhere, inside and out. Everything we needed was within a short walk (24 hour supermarket (Carrefours) right around the corner, metro stop too, coffee/breakfast shops, pharmacy). Every kind of restaurant and taberna within walking distance. Not kidding. We stayed for a week and weren't able to even scratch the surface. Walking distance to Reina Sofia (about 15 minutes), Prado and Thyssen (about 20 minutes). Lavapies Metro stop is around the corner, so we took the train quite a bit too. We didn't have any need to contact the host during our stay, but she was very responsive and helpful in advance. We will definitely stay here again.
