Bring ear plugs! We read other reviews before staying so knew that it was going to be loud as right in the heart of the Old Town, but it’s incredibly loud outside on the street into the early hours of the morning. Location worth it though!
Apart from that, the flat was incredibly clean, modern, and spacious - and perfect for our needs in San Sebastián. The only other minor flaw was that there were no mirrors in either bedroom which would have been a nice touch.
Check in was slightly disastrous as the bluetooth app was fiddly and didn’t work - had to ring Feel Free at 9.30pm to open door remotely.
All in all 4/5 stars as had a great few days! Just some minor faults :)
