This flat's got a perfect location for a short stay in Madrid. Located in the core of Malasaña, you'll have everything you need 100m around : good restaurants, markets, nice bars and beautiful streets to walk around.
Juan is a very reactive host who will answer to your questions in the hour. Thank you again for the early check-in !
Only one thing, the 2 big rooms are on the main street which can be a little bit noisy on friday and saturday nights.
But you'll have a good bed to balance that ! ;)
