Rented the flat for an extended stay business trip. Having been to San Sebastian previously, this was a perfect location to everything I needed. Located very close to nearby grocery store as well as parking garages and bus stops. The flat is less than a 5 minute walk to La Concha and very close to Old Town for dinner and pintxos. FeelFree answered all of my questions promptly and were flexible when my check-in was delayed due to flight delays.
A few reviews have mentioned noise. This location was slightly noisy due to street cleaning and garbage pickup vehicles as well as late night bar goers to the Old town, but overall I did not find if disruptive. A must stay for those looking to be in the city close to all of the action, but may not be the best for those looking for peace and relaxation in the evening.
