Very cosy and homely even though the hosts don't actually live there. The apartment was very clean and there is an incredible view from the window. Both the shower and heating are very good. Despite being one room there is plenty of space to store bags etc. One thing to note is that the noise insulation isn't great, but this isn't really a problem as the neighbours seem quite quiet. The space around the toilet is a bit tight, which we were ok with but it might be difficult for a taller person.
The hosts (Anne-Marie and Paul) are very friendly, providing breakfast supplies (!), giving extensive recommendations and were very available to answer quesions (they live on the floor below).
The apartment is in a good location and most of the main tourist attractions are within walking distance. Overall a really delightful apartment in a nice old building and we couldn't have really asked for better!
