Mikkel is a very welcoming host and lives nearby. He was very quick to answer any queries. The apartment is superb, clean and spacious, well able to take two adults + 2 kids or 4 adults. The view to the city can only be described as spectacular and we spent a couple of lovely nights on the balcony appreciating it. However, with the view comes the trip up the hill to the apartment. The main road is very steep up to it, or you could use an alternative pedestrian route with a lot of steps (not usable if you have small children and a buggy). Driving to the city can be difficult as well, as parking can be hard to come by in San Sebastian (we had a hire car and Mikkel has a very secure garage that we parked in). With all that said, an adult walking could be in the Gros area within 5 minutes or at the old town in 15 minutes, which are the main pinxtos bar areas. I would definitely see us using this beautiful apartment again, but whether we would bring the kids is something we would have to think about.
