We just spend a week end in Juanfran's apartement (3 friends) and it was a great option to explore and enjoy the beautiful city of San Sebastian. The apartment is pretty big, cosy and clean. It is possible to park in a free parking very close to the apartment if you have a car. To go downtown, the center and beaches are just about a 25/30 minutes walk, but there is also a bus to go and come back directly from the city center. Taxi is also a fast and cheap option to go back to the apartment from downtown. Beds are comfy, and the neighbourhood is very quiet at night which was great for us. We didn't get to meet Juanfran but we met Marian, his sister, and all comunications went very smoothly, by email or whatsapp. We highly recommend Juanfran's place to stay in San Sebastian!
