The flat is comfortable and quiet. The main room is a very pleasant space with a large table which I found useful as a desk. The two bedrooms and the bathroom (toilet/shower) each have doors directly onto the main room. In other words the flat is rather compact. The flat is on the first floor from the street and one bedroom and the main room look out onto a large courtyard (on the first floor of the courtyard) whereas the other bedroom and bathroom look out onto the ground floor of a small courtyard (protected by metal bars in the windows on that side). Because of this the flat is very quiet (although I was actually hoping that the flat had a street side as I enjoy that contact with the city). It would be useful if these details were up on the Airbnb page.
The flat was also fairly sunny on the main room side (August) and was very clean. The location of the flat is excellent - central and also 15 minutes walk from the old town. The personnel of Next Stop who run the flat were very helpful and provided us with considerable local knowledge/advice.
A caveat: the wifi is passable but it would be better to have more bandwidth to be able to stream videos and upload material comfortably. Also I banged my head at least once a day against the water boiler in the bathroom so watch out for that.
