This place is gorgeous! The location is exactly as described and the historic building is a treat. Yes, there are stairs but the building is over 300 years old - there are stairs.
I would 100% stay here again - the hosts were excellent with their communication even though I was often unavailable to answer as quickly. The check in process is simple and everything you need for a memorable stay is there.
If you are having people sleep on the sofa then they will have to deal with noise. If you are just using the bedroom you will have peace and quiet and a comfy bed.
