This apartment is in a very good location with a beautiful view. A short walk away down the hill and down a (large) staircase you are already at La Concha beach. It's about 20 to 25 mins to walk to Parte Vieja or Zurriola. There is a grocery store and cafe near by.
The apartment itself is quiet and clean. The stone floors and carved solid wood give it a bit of a luxury feel, but there are some things here and there which need to be repaired.
There are 7 rooms in total so you are sharing the space with many other people, but they are all there for longer stays so there were no newcomers arriving during my stay. Also if you are there on vacation, the other tenants are generally out in the day (e.g. work) so you will not encounter them often if you are. They were all friendly and considerate.
There were 2 bathrooms with showers and one bathroom with just a toilet. It seemed like enough and there wasn't often a wait to use either. Strangely, one shower did not have a shower curtain.
This room does have a small desk in it which is definitely enough to do work on, however, the internet connection was spotty via the repeater and this meant on most days I actually could not get internet in the room and had to work in the common area (which was also fine).
