We were a couple with our son and we all liked our 5 nights stay...the apartment served us well and had all what we needed!
Some people my like to know that there are 40 stairs to reach the apartment from the street and it does have windows but they are facing internal yard which not have much fresh air.
The Market in front of the apartment is wonderful you should try the Spanish Omelet at Casa Dani inside the market!
Enjoy
