We had a most enjoyable visit to Barcelona (our first time) and found Oliver's apartment perfect for our needs in a pleasant residential area, with shops and La Sagrada Familia nearby. Oliver met us at the flat and gave us a guided tour and then gave us a detailed virtual tour of the city, marking places on the map that he thought we should visit and restaurant recommendations - and also warnings about where not to eat and to be careful of pickpockets. All very helpful. Thank you.
