I stayed in Elena's apartment with my parents for 4 days. This place is perfect for 3 people - very convenient and enough space for everybody.
Elena met us even when we arrived late and gave us good instructions about the apartment, which was handy. The apartment is perfectly equipped and we had everything we need!
The location is great as well, as it close to Diagonal metro station and Gracia district.
We found good restaurants near by. One of them - a coffee place Onna Cafe where they serve great coffee and very good lunch for only 8.5 eur.
We enjoyed our stay and I absolutely recommend Elena's place to discover Barcelona!
