Considering the price, I would rather stay in a hotel. The terrace has a beatiful view and the location is very good, next to El Retiro. That´s about it.
Not comfortable to stay longer than one night. Key elements were missing: long mirror, ironer, closets, Etc. The bathroom is very small, almost no place for a tooth brush.
Neighbouring apartments are being built /refurbished and sometimes the noise is unbearable.
The washing machine was leaking.
I would not choose to stay there again.
