My wife and I stayed at the apartment for six nights with a couple of family members. The apartment is very well located in the center of Bilbao, close to everything and on a relatively quiet side street with a very good restaurant a few feet from the front door.
The front room is large and attractive. The two bedrooms are well back from the street on a narrow corridor so isolated from any street noise there might be, but walls are thin otherwise.
The master bath has no door to it, which means no privacy using the toilet, and leaving the shower is chilly. Also the mirror over the master sink is not great for shaving.
Lastly, there seems to be a problem with biting insects in the master bedroom. Those sleeping in the smaller bedroom had no issues, but my wife and I slept in the master bedroom and woke up every morning with new bug bites. We weren’t able to locate the source of the bugs, however hopefully this can be rectified.
