Great location in the heart of the city.
Fantastic little place to stay for a night in Bilbao. It is so clean it felt like I was the first to ever stay here. Bed is standard double (I think) so big enough for two though I stayed alone. Room is well equipped.
It is on the first floor above a bar in the square and so can be noisy until late, but this was expected with the location so I was prepared. Not a complaint, just a reminder to others.
The only issue I had here is very minor and is likely AirBNB issue rather than the venue. The host requests filling in a form before checking in but doesn't send the link to the form with the email so you have to ask them for it and then it takes a while. I couldn't wait that long and so checked in anyway and filled the form in after. The host seemed to be ok with this but I wish their original message had mentioned it or included the link as after a stressful journey it was another issue I didn't need. Maybe it is an AirBNB issue that they don't let hosts send links on the original message. Anyway as you can see this is a minor issue and if you know it ahead of your stay won't be one for you.
