The flat is in a great location and easily within walking distance of green space, city views and the gothic quarter (where it's nice to get lost in the lanes). It's also really near metro stations, cable car and a lovely road with loads of tapas and pinchos bars and restaurants.
The flat itself was a good size and had everything we needed. Checking was easy and they provided a great list of recommendations for places to eat and visit.
Overall a fab stay in Barcelona and great flat. Would stay here again!
