A great place to stay in Barcelona! The flat is very cosy while still offering enough space for 2-3 people to not feel crowded.
The flat is within walking distance to the Sagrada Familia and is next to a metro station. Hop-on-hop-off tourist buses also stop next to it due to the Recinte Modernista de Sant Pau on the opposite side (very worth a visit!). The adjacent pedestrian Av. de Gaudi features lots of eating places and small shops.
The flat came well-stocked with everything needed, including lots of towels, a washing machine and some spare wall-adapters and extension cords. Air conditioning works but only covers the living room, not the bedroom (cooled via a window).
As others have noted, the flat is generally quiet but the building's elevator is pretty loud. For us it wasn't a problem since we were out all day anyway and the elevator is rarely used at night. We had no problem sleeping through busy mornings.
Thanks again Pep for the great stay!
