We had a wonderful time at Nicolas place which is quiet and even spacious for a Spanish flat in the city centre! It's perfect location was absolutely outstanding and we could reach a lot in walking distance even with little kids!
Moreover, the flat is well stocked with all what you need, also a washing machine! And there is an elevator, too, which makes travelling with luggage (an kids) so much easier!
Nicolas and the team in Barcelona where always reachable and internet was working nice too!
All in all, it was a very great experience and we would be definitely back and recommend it to everyone!!
