A great, spacious apartment which was more than comfortable for 4 adults we had staying. Could sleep a further 2 if needed. Decent sized master with ensuite (although it was a little squishy but still usable) and a 2nd and 3rd bedroom with bunks in once and 2 singles in the other. Main bathroom was fine and central to other bedrooms and living space.
The terrace was fantastic, it was very big which was great to hang out and see over the city. Could be a little dirty however this is due to the Barcelona traffic etc and not due to being kept unclean. Only thing to note is there is no under cover so if it were to rain it wouldn't be practical but we had great weather and so used it daily.
The kitchen had everything we needed, aircon in the lounge and also in all 3 bedrooms.
check in was really easy with the electronic access. The lift is very small so needed a couple trips up and down with suitcases but again, all a part of travelling - just grateful there was a lift as it's quite high up!
Would certainly book this accommodation again on return to Barcelona.
Great location, 5 min walk to La Rambla and down to the water front. Convenience stores within 1 min and restaurants across the road.
