I had an excellent stay. Unique Stays has excellent communication and responsiveness, and they are very friendly as well. The apartment was comfortable, and although I didn't cook during my 3-day stay, the kitchen is well appointed and would be great for longer stays. One very important point for me is the cleanliness of a rental, and this place was spotless.
The location could not be better, a quick walk from stores and restaurants, and to public transportation. Although the street is busy, noise was not an issue. You can hear people in the upstairs flat when they walk around as that noise is pronounced, but it wasn't really an issue. You should also know that the stairs into the apartment are fairly steep, so it's a little awkward to navigate with suitcases.
I would absolutely stay here again, and recommend Unique Stays highly. Five stars!
