We stayed in this apartment for 4 nights during Tiff. Effy was very accomodating before we arrived. In the weeks before we got in, we added a guest and 1 night to our reservation and everything went smoothly. The apartment is superbly well located. However, it was a little small for 3 guests (a couple and a friend) and the fact that the bedroom only has glass doors is not ideal for privacy. This also is clearly a "living" apartment as opposed to other Airbnb apartments that are clearly more hotel-like in their furniture and decor. Effy was accomodating with the time of check in and check out and was easy to get in contact with. I found the overall price was a little high but during Tiff, all apartments and hotels are expensive.
We are, overall, statisfied with our stay at Effy's place.
