This place is quiet and clean and has a lovely garden. There is also a nice selection of snacks and non-alcoholic beverages, plus a mini-fridge and microwave. The bathroom is particularly nice, great shower, heated floors, separate WC.
If you have any difficulty with stairs, this is not the place for you. Also while you can walk to the rose and Japanese gardens, it's not an easy walk for everyone, and restaurants and other activities require a drive.
