A lovely place to stay! It is a little compact, but you have everything you might need. Stayed there for 2 weeks and worked remotely the whole time, so I appreciated the dining table that could be used as a work table as well. The big Brivibas street is near, but the windows face towards the inner courtyard, so the noise was not intrucive.
The only thing to take into account is that the building does not have an elevator and the staircase is narrower than usually, so getting to the 4th floor with a big suitcase (like in my case) takes some effort.
Overall a great stay!
