We are a family of 5 (3 young children). We've just spent two nights in Alex's apartment.
Its a great place. Very clean and neat. Nicely decorated. There is plenty of room, a great kitchen and large bathroom/shower. It's close to everything. Public transport was not required.
Alex is a very good host. He has responded to all my messages within minutes. His sister Laia met us for check in. She was very friendly and provided us with all the information we needed. Alex has even put together a very informative tourist information booklet which is very helpful and very thoughtful. :) All airbnb apartments should do this.
We loved our stay and highly recommend Alex's apartment.
We hope to return one day.
