We stayed 4 nights in Gracia and it's a great location for staying whilst visiting Barcelona. A short walk to Guell Park and Sagrada Familia and easily walkable to the other sites if you wish - there is a metro station on your doorstep for those who want to take public transport. Gracia is a fabulous area to spend your evenings. Lots of great tapas bars, restaurants and bars within 5 minutes of the apartment - start your evening by watching the sunset from your balcony. The apartment is at the back of the building so peaceful and great views from the balcony.
