The location is great, short walking distance (10 min), and right between the old town or the Guggenheim area, also 2 min from Ledesma street for pinchos and bars. The room is as it is shown in the pictures, and equipped with pretty much anything you may need. Else, I believe that Sonia would be happy to provide any other thing.
However, we expected that private bathroom would mean an ensuite bathroom.
The bathroom, while exclusive for us, was located in the corridor, which meant that if you want to pee at night and are sleeping in your pijamas/underwear, you will have to go outside the room. Nevertheless, the house was extremely peaceful, and we hardly had any interaction with other people, which is what we expected.
To conclude, value for money is good. However, the listing description could be made a bit more accurate.
