Marcye is a wonderful host. Anytime I had a question or request she responded virtually immediately, and was more than willing to go out of her way to make my stay as pleasant as possible.
The flat is superb as well. It's much bigger than the pictures suggest, it's spotlessly clean, stylishly decorated, and the location is excellent.
There wasn't much that was negative, but if I had to be particular there was construction going on all hours of the night. It wasn't too loud, but it is noticeable.
All in all, highly recommended.
