Wally was a great host - communication was very efficient and he welcomed us to the flat himself and gave us a great summary of good things/areas to visit in Barcelona with a map. The Sants area was perfect for us - within walking distance of Camp Nou Staduim and Sants station and Placa del Centre metro - so it was really easy to zip around the city. The street has a great local feel with cafe's, patisserie etc so it is easy to pop out and get anything you need, including breakfast.
When my son left his mobile phone in a taxi, we thought we would never see it again but I thought it might be worth seeing if Wally could help. He was amazing and he managed to track the taxi down (always keep your taxi receipts!) and personally brought the phone back to us within a couple of hours of the loss. It really made our holiday - what a fantastic Airbnb experience!
