We had a great time! We really felt like home in Hector's flat. It was our first experience with Air Bnb and I must say I'm impressed. Hector and his fiance were really helpful and nice, answered quickly to all our questions and needs. They gave us great recommendations for shopping, restaurants and public transportation, which were all nearby. The apartment is located close to the beach - it took us about 10 minuts to get there, and it also has an easy access to the subway. The city center is close, about 15 minuts by subway, but we ended up spending more time in the Poblenou area, which has its own Rambla, more quiet and pretty nice :)
The apartment is very well distributed, we were 4 people and we had our own space and privacy. It's very polished and clean, they provided us with bed linen, towels, hair dryer and other details we appreciated. We had all kind of cooking utensils, washing machine and dryer, free wireless internet, phone and central heating. The weather was nice and in the morning the sun heated the flat nicely, so we didn´t use the heating much. I was a bit worried because it is located on a 5th floor, but I must say the stairs weren't a problem, as they are very confortable. There is a free parking lot right behind the building, which we found very useful for our rented car.
All in all, we really enjoyed our stay and we will definitely be back!
