The six of us had a wonderful stay at Vadim and Elina's apartment. The apartment is a great size, comfortable for a big-ish group and well-located in terms of public transport and restaurants/shops. We didn't spend very much time in the apartment, but it was a great base from which to recharge and to explore the city from. I don't have a single complaint and I would definitely look to stay here again if I revisit Barcelona. Thank you very much Vadim! :)
