If you want to be in the middle of it all, this is the place to stay. It is very cute, but know that it is QUITE small and the pictures don't really show this. It was clean and the bathrooms and kitchen were furnished with everything we needed. We didn't use the washer because of our short stay, but did use the convenient clothes line to air out our belongings and get them fresh smelling after much travel.
The quality of the apartment is quite nice with up to date furnishings, soft clean towels, lots of wood, and a clean, very clean, environment. That said - the couch is the only place to sit and the lighting is difficult - not conducive to reading. This is not an issue if you are planning to be out exploring most of the time. A few hints - the hosts are clear that this is a busy and noisy part of town - and it is - but if you close up the wooden shutters that blocks a lot of the noise. I wouldn't recommend this particular apartment unless you are single or a couple who sleeps together. The small extra bed is NOT good quality - the mattress is thin and the frame is missing a slat. The stools at the small table are hard and don't have cushions - so if you plan to be in the apartment very much, there aren't many places to sit comfortably and relax.
Finally, the description offers early check-in for bags and even though no one was in the apartment the night before, it seemed that could not be accommodated. So we had to leave our bags at the train station and then go back for them. It is very hilly there and it was a very hot day, so this was exhausting for us. Probably it would be best not to make the offer which raised expectations, only to have them dashed.
