I spent three weeks in the studio and overall i really enjoyed my stay. Its is charming, really nicely decorated and perfectly situated. Ideal for 1 person I would say (Be aware that if you are in couple or more, there is no proper door closing the toilet :-)
The only downside is that the kitchen missed few things to be really fonctional as i cooked a lot while i stayed there. And also it can be a bit noisy as it is situated on the ground floor, and few bars are nearby. But in Madrid it’s hard to find streets without bars anyway :-)
i really recommend this studio!
