We loved this apartment. The host gave us clear instructions, a lot of recommendations, shared website with tips and left for us a touristic guide (book) with the highlighted things to do in Barcelona.
The place is cosy and has a lot of space. The kitchen is fully equipped (even with a dishwater).
Apartment has a great location. Only 10 minutes walk to the Sagrada. A lot of good groceries stores around and only 5 minutes walk to the Subway.
We highly recommend to stay here. You will have a feeling that you are at home.
