Yes, Very comfortable stay. Everything was perfect.
We enjoyed our stay in Barcelona in this stay. The house is exactly a listed, with all amnesties. The house is in very comfortable location, just a 2 minutes walk from Central Bus station "Barcelona Nord". This was very comfortable for us, as we had travelled to Valencia by ALSA bus. This bus was departing and also arrived in this bus station in midnight. it was very comfortable that our house is nearby.
There is a good very big super market "Mercadona" nearby. Also, a small super market just in the ground floor, and also nearby there are a lot.
Sonia was helpful in clarifying all questions I had, though we didn't meet her.

One hint on Arrival :
If you are arriving in Barcelona by flight, in El-Prat Airport, then It is very easy and cheap to reach apartment by train. Just take T10 ticket ( 9.95 EUR for 10 trips in metro/tram/bus ), and take Renfe R2 train from Airport and get down at "Barcelona-Clot-Arago" station, from here take Metro Red line, L1 and get down at Arc De Triomf. All these journey (yes, both Renfe and Metro trip in one punching! ) allowed in one punching of the card. Means, for around 1 EUR, you will reach your apartment, from Airport !
