It is a 5star place. To me it is located in the best, central part of Madrid. Walking distance from everywhere. I enjoyed the best parts that Madrid has to offer :) If you need a metro it is a few mins walk.
The apartment has high ceilings, huge windows, spacious bedroom with a bathroom. Additional guest bathroom is in a living area. It is in a very nice, charming very well preserved building with huge wooden entrance doors. It was super clean when I arrived. It is fully equipped, very cosy, with additional blankets and pillows. You can regulate your own temperature inside. Liron was the best host, he travels a lot but is always very responsive.
The apartment itself is very quiet, there was not a sound from the neighbours. Windows block the street noise because please note that it is located close to bars and restaurants. To me one of the best AirBnbs I have stayed in, I actually extended my stay and will definitely be back. :)
