We had a brilliant stay! Eyuan was very helpful and responsive before and throughout our stay, offering clear and helpful directions on checking in. We found the use of the smart lock very helpful and secure!
The location is ideal for exploring the old town as well as getting out into the city - it's a 2-minute walk from the metro/euskotren station, and only 5 minutes maximum walking from the shopping area.
As we had poor weather, we stayed indoors more than we had planned, but the flat had all of the useful amenities to pass the time.
We'd definitely come back and stay again (hopefully in better weather!)
