Absolutely fantastic. Location is brilliant and most things in walking distance so no need for a metro pass. Apartment is absolutely spotless and has everything you could need. Very comfortable bed and super nice shower. We didn’t have any problem with noise and felt extremely safe in the building. Most importantly, Paola and Arturo were such wonderful hosts - very quick to reply and also flexible and understanding when we were unexpectedly delayed arriving. They were also very helpful during our stay. Can’t recommend this place enough if you want a clean, comfortable stay at a very good price in Madrid!
