"The top floor is a lovely apartment. But it has a narrow staircase and might not be suitable for guests with physical challenges."
"I believe there is one room with a kitchenette, but I did not stay in it."
"All rooms are nice, but very individually designed and accommodate different numbers of people. The one-bedroom is really small."
"the room/suite at the second floor is very large and has its own kitchen"
"Could hear early risers leave from room(s) above us"
