This was the nicest of the 3 AirBnBs I stayed in during my time in España and easily one of the top properties I’ve stayed anywhere in the world (between the US, Japan, Portugal, Spain).
Amazingly updated/maintained/clean third floor apartment in a private building with an elevator and doorman.
The street is a single lane, one-way street, so arriving during busy hours means you will need to be expeditious with offloading your suitcases and moving your vehicle.
Location is about 200m from Puerto de Alcala (northwest corner of El Retiro Park) and 1.1km from Prado Museum.
Plenty of top rated restaurant and nightlife options in the immediate vicinity.
Very easy COVID testing for your travel is located within 350m (Clínicas Vieco, €40 for a 15-min Rapid Antigen result, no appointment required).
Would highly recommend staying here if you don’t mind being a little east of the main tourist attractions of Madrid (Royal Palace is 2.4km but only ~€10 on Cabify).
I will definitely stay at this property again if I’m in Madrid.
