The location of the apartment was great, it has only been 1min to the beach and the view from the balcony was nice.
The kitchen was well equipped with all the stuff you need to cook. The rooms were spacious and well equipped.
There were also some minor negative things:
The floor wasn't that clean, but all in all not a real problem.
A major issue was that the aircondition was only working in one room and so the other bedroom was very hot during the night.
We informed the host and they said the aircon should be working soon but for our stay it was too late. i hope they fix the aircon for the next guests.
But all in all I can highly recommend the apartment and a holiday in San Sebastian.
