We stayed end of October for a 5 days. Their were 5 of us. The flat is really spacious, comfortable and has plenty of light. We had all what we needed. Many restaurant around. Walking to the old town takes just 30 min. We did it both ways several times during our stay. Beds are very comfortable. Just be mindful that one bedroom has no doors;
The flat is very practical and convenient. The contact with the owners was really great. They are very reactive, accommodating and responded to our communications within a few seconds.
A way to improve the flat, would be to add a few more decorations, such as pictures on the walls, or some books. This would make it a bit less impersonal.
