Andrea's appartment is perfectly situated, especially for those, who want to visit Gaudi places. Some things you can reach by a little walk, or very easily with busses or metro.
There is enough space for 4 persons, and the bed as well as the sleeping-sofa have good matresses.
The furnishing is very special, a mix of bic-a-brac market and a modern, sparkling kitchen, really imaginative and creative. The balcony of the living-room is very spacious and we enjoyed the evenings there, in silence and with a glass of vine.
Andrea himself is a very friendly and helpful host, and he even answered to my messages in the middle of the night, which I didn't expect.
If I would go to Barcelona a second time, I would choose this place again.
