My wife & I travel a lot, so have very high standards & expectations for places we stay.
Atari Hotel was a great hotel in a perfect location with all the amenities you need when travelling.
The room was comfortable, spotlessly clean & (after 5+ weeks of travelling throughout Spain) had THE BEST shower I have ever experienced in a hotel.
The only issue I could find throughout the stay was that the room doors had spring vlosing functions which made them slam shut (very loudly), which made for the occasional abrupt 'wake-up call' during the night or early morning.
Apart from that minor issue, we loved our stay here.
The staff were all super friendly & helpful, breakfast was great & wirth the extra money and we would definitely stay here again when we are next in San Sebastian.
