I spent a lovely stay at Wilson house.
The room was pretty clean. The staff was very kind and attentive. They have tried to make us feel at ease. The bathroom is shared so the cleanliness depends on other customers. Hopefully the bathroom was cleaned everyday so it was highly appreciated.
I would not really recommend the room for 4 people as the sofa was not confortable. If you are sensitive to noise be aware that you may hear other customer walk around in the flat.
