If it hadn’t been for the beds I would have rated this Airbnb more highly as our room was beautifully situated, our hosts good at communicating and everything else was satisfactory. However I was traveling with a good friend and we asked for separate beds. The single bed provided was so hard that I woke about every half hour in pain. I did ask for this to be remedied. A simple short term solution would have been to provide a foam topper for the bed. The second night the only solution was to both sleep in the queen bed which although comfortable enough was very creaky.
I hasten to add that I have had no trouble when visiting Japan sleeping on Futon mattress on the floor.
If this problem was remedied I would without hesitation highly recommend this Airbnb. It is very reasonably priced, close to everything in the most charming area with views over the water and Sandie was a lovely host.
