Will is a super nice friendly guy with positive attitude. We liked the apartment, but there were minor issues which I have to tell about to fellow travelers:
1) carpeting while not dirty does seem a bit dusty and requires thorough vacuum cleaning
2) Accuracy of photos - room we stayed at was different to the one shown on the photo (different bed arrangement, and two windows at the photo instead of one in actual apartment, different blinds than the one at the photo).
3) blanket and pillows were not same as represented at the photos and were not very comfortable.
4) as mentioned by other guest - there are street noises and can be noises from neighbors upstairs/tv/high heels in the morning from. not loud, but worth taking into account if you are a sensitive sleeper. I suggest bringing earplugs.
All in all, it's a fine apartment with cool host and I would recommend it once those minor issues are addressed.
