This was a good apartment in the centre of San Sebastian. The apartment was clean and to our satisfaction. It has to be noted that whilst there is a spacious double room with natural light, the second bedroom was smaller and only had a commual courtyard for natural light - since this was communal we kept the curtains closed at all times for privacy reasons so we had no natural light in this room.
The 3* rating is for a bad check-in experience. Firstly, all members of our party had to scan our passports into an unknown app which we were not comfortable doing as we had never heard of this app before. Secondly, upon arriving at the property, the door did not open via the app so we had to call the owner to be let in manually. If we did not have signal or if the owner had not picked up the phone, we could have been left waiting outside for an indefinite period.
