We had a wonderful stay at Ana's adorable studio. It is little but feels cozy and is so bright and homey. The size was never an issue. It was very clean and Ana was sweet enough to leave us juice and muffins.
The location itself was perfect. Walking distance to everything! The street itself can get very loud at night though with the balcony doors closed it was not so bad. It did get a little hot inside without the windows open at night so my only suggestion (really my only one! Everything else was perfect) would be perhaps a small fan!
Thank you Ana! We will definitely stay here again if we ever return to Madrid.
