Aster House

A lovely place to stay — very clean and quiet. Charming inside and out. We stayed 7 nights. The bathroom is really tiny, and they serve the same thing each and every day for breakfast. Otherwise a real gem.

Stayed at Aster B&B for seven days in March 2015.

No elevator, but I only brought a backpack. If you bring rolling luggage, you will have to carry it up several flights of stairs.
