Cute and calm little endroit a few minutes from Atocha station and walking distance to Lavapies and all its bodegas and restaurants. Busy street but very good sound insulation - it was actually nice to be in the hustle and bustle of things but still sort of serenely cut off from it all. Check-in is a little fiddly but not a problem, you just need to follow the instructions despite friendly neighbours offering to help out :) All in all a great stay and perfect for a brief trip to Madrid!
