The apartment is extremely close to the station, in a quiet square. It's a bit termed from the hustle and bustle of the tourist areas but not so far away that you need to walk a lot. There is no elevator. The stairs are higher than normal. We had 4 old persons in our group, all of them had some trouble walking up the stairs.
The apartment was extremely clean and the beds were comfortable. The attic bedroom is really for kids and not suitable for adults. Tall adults like me (185 cm) will tend to bang their heads if they aren't careful.
We had some trouble during check-in as the power sockets were not functional due to some problem in the kitchen area. Irene was very helpful and had the problem fixed within 2 hours of our arrival. She also made sure that we were suitably compensated for our troubles.
The apartment is thoughtfully furnished, has a great location and was extremely clean. We might visit once again if the chance arises.
