At first, I want to say that the host is very friendly and kind man. He will help you at any times.
The location is near to metro(Clot) and local train(Clot-Arago) so it's easy to visit the central Barcelona and Airport.
The environment around the house is quiet but inside the house it is easy to hear other's voice and sound.
Unfortunately there was someone who doesn't follow the house rules. Especially for the NOISE. Sometimes I was frustrated and annoyed. The problem wasn't fixed during my stay.
However, I want to lay emphasis that the host is very nice guy.
