My mum and I had a lovely time at Vali and Simona's flat. Vali was there when we arrived and gave us a tour - the place was very clean, big and airy and we had everything we needed. The front bedroom was a little noisy at night but otherwise very quiet. The location itself is great - a gentle 20 minute walk to La Rambla (Placa de Reial where we picked up the free walking tours) or a short walk to Carrer de Blai for some yummy food. If you're planning to go to the beach a lot then it's a bit far away but for everything else you can probably walk a lot of places and there are several metro stations within a short distance.
