The flat is great and the owners (also the housekeeper) were very helpful. It was extremely clean and well maintained.
Only two small issues. It's up several flights of stairs. This would be fine for most people but less good maybe for some older guests or people with movement difficulties. Also there is a bar down stairs which had a loud band who usually struck up around 21.45. This could be a little disturbing if you go to bed fairly early.
As I say tho it's a really good flat.
