Basically and most of the time a great place , you will find a lot of what Madrid has to offer at walking distance. The apartment as such is cute , two good beds , two bathrooms , a washing machine etc ,but be prepared for less than 10 minutes of warm water and having to wait 60 minutes before it is warm again.
The apartment is far from sound proof and a bunch of airbnb neighbours had to be calmed down by police after two sleepless nights. But also simple talking left us desperately in our beds.
