Good price for the room, and while the room itself was quite loud, it was in a great location, clean, and good for the price.
Location is in Gros, which is quieter than the other more central parts of town, but everything in San Sebastian is so easy to walk to that I was glad to be there and not in the crazier touristy neighborhoods. 15m walk to the old town.
Host was not on site but she communicated very well, and the procedure for getting the keys was clear. Apartment was clean with a kitchen and a washing machine, and the other guests I met while I was there were very nice. My one complaint was how loud room #4 could be, at least during the daytime. The walls are thin and you can hear everyone coming and going, and using the bathroom. Now this was also one of the most affordable rooms I could find for my stay, so on balance it wasn't that bad.
