We were granted by hosts a very nice hospitality, support and flexibility in the checkout, during our staying.
The apartment was great, actually bigger than we needed for a 4 person family. It is well decorated and furnished with everything necessary. The appliances were new and working properly as well as the furniture. The localization is in the middle of the most famous attractions of Bilbao, at walking distance.
The only thing is that is necessary to describe better the quality of the garage. For an intermediate car , as I was driving, it is almost impossible to use due to the narrow and curved access. Although being a very skilled driver, I had to have my wife outside guiding the way to not scratch the car sides. The distance to the wall in certain points was around 1 centimeter, and there was great stress when a neighbor entered, while we were trying to go out. We were forced back and only fortune avoided the worse result. But if you are driving a small car or is extremely confident of your driving abilities, it may work.
