This is a professionally run apartment. All the big things are good, but also small details are taken care of.
Location is great in heart of Old Town ( many restaurants, bars, shops)and close to the beautiful beach .
There is no air conditioning, but there are a couple fans. It can be noisy at night as you get to the weekend. The windows cut out a lot of the sound but some gets through. We were able to sleep, light sleepers might find it a bother.
Edurne was very nice answering questions about the area services etc. Overall a great place to use as home to explore San Sebastián.
