Well, this was my first time with airbnb and I'm totally happy.
Jaume is a very nice host, after I booked his place he responded very quickly and checking in was totally easy. I contacted him by text message when I arrived at the airport, so he was there when I arrived at the flat. Quickly explained everything, gave me the keys and I was ready to enjoy my stay.
He is very quiet, I never really noticed when he was home, so it felt as if I had the flat for myself. The apartment has a nice living room, normal kitchen and a good sized bathroom. My room had a comfortable bed and was big enough for 1 person. Jaume provided nice towels.
But the best thing is the location of the flat. Gòtic is pretty central and you can reach a lot of interesting location just by walking. You can quickly reach La Rambla, quite famous shopping street but Gòtic has also a lot of small streets with little boutiques and nice restaurants.
The next time I travel to Barcelona I will definitely try to book Jaumes place again.
