The apartment is very cosy with nice design and has perfect location. All worked well and it was easy to communicate with the host. It is perfect for a family (we are two adults and two kids). Only negative thing was that the beds in the smaller bedroom were not comfortable and were very squeaky, even our kids were complaining about it. The main bed was fine.
The location is perfect for exploring Barcelona, close to the main attractions yet in a quiet local neighbourhood. There is a market and supermarket one block away so it is very easy to make breakfasts or other meals in the apartment.
