As other reviews have noted, this Airbnb overall is spectacular for its price considering its location right in the heart of Old Town in San Sebastian.
This is a single private room in a Guest House flat that contains at least 5 rooms and 2 shared washrooms. I rarely had to wait to use one of the two washrooms and the Airbnb room and washrooms were clean. The host was great to communicate with as well.
The only 2 cons I can note were first - the thin walls where you could hear your neighbours conversations and more... *winkwink* - they do provide free ear plugs which helped solve this problem. And secondly, the unreliable Wi-Fi internet - connection issues on multiple devices, fluctuations with the internet speed but most of the time it was slow or not functioning - we had daily issues regarding this during both day and night time.
Overall given the price, this Airbnb is highly recommended! Will consider staying here again in the future for more vino and pintxos :) also, the local pintxos guide map that was provided amazing and much appreciated!
