Luis and Terese's flat is gorgeous - it's bright, beautiful, spotlessly clean, well equipped, looks exactly as it does in the pictures, has great views of the city and mountains, and is in the perfect location for exploring San Sebastian. We were right in the center of Old Town, so we had some of the best restaurants in the city within steps of the flat, and were able to walk to both beaches within 5 minutes. The flat is on the top floor (so it has great views and lots of light) but the building has a lift, which was perfect as we were traveling with our 17 month old daughter and had a small stroller with us - much easier than taking 6 flights of stairs to the top floor! We had a small mix-up when we arrived - Luis was out of town so he arranged to have a colleague greet us and let us in the flat. Unfortunately she was delayed and had phone trouble so we weren't able to find or reach her when we arrived. I got in touch with Luis and he was extremely responsive - he sent someone within 10 minutes to let us in the flat. He even made reservations at a great restaurant near the flat for us and had a bottle of champagne waiting as a gesture for the mix-up. These things happen, it was not a big deal, but Luis went above and beyond to fix it and make sure we were settled in. We couldn't have been happier. Luis and Terese sent recommendations for things to do and restaurants to try ahead of time and during our stay (all amazing), he was extremely responsive to all of my questions (he would always respond within minutes), and he even helped research a place for my husband to rent a mountain bike while we were there. Luis and Terese really went above and beyond to make sure we enjoyed our stay and experienced the best of San Sebastian. We absolutely loved it there, and can't thank them enough for their hospitality. This was one of our best airbnb experiences so far, and we will definitely be back to stay at their flat!
