We had a great stay in Pilar's apartment, which is situated in Gracia an area close to Sagrada Familia, Guell Park and in a district that is served well with book shops, boutique art galleries, cafes and eateries.
Transport is easy with Metro and buses only a few minutes away.
The apartment building is substantial and in good condition with a small lift in good working order, but apart from the first and last day with suit case we used the stairs as the apartment is only 2 floors up.
The actual apartment is spacious, and has all the facilities that one could reasonably expect. The WiFi worked well.
We were made to feel very welcome by Pilar who had communicated well with us during the period of finalising dates times etc. She was most helpful with all aspects of our stay.
We thoroughly recommend this apartment, and if we return to Barcelona, we would look no where else to rent.
