I spent a week together with my wife at Shawn's apartment, and we had absolutely great experience with everything. Communication was easy with Shawn, both before the trip and while staying there. She provided detailed instructions in digital form before the arrival, so we had a clear picture what awaits us. She was waiting for us in the apartment when we arrived, and she was also available via chat during the stay, where she responded immediately in case we had any question. The apartment was just like on the pictures: well equipped, sunny, clean and tidy. We had to climb some stairs to get there, but that was only challenging with the luggages. The bed was comfortable, the bathroom was clean, in the kitchen we could find everything we needed, we could eat on the big table in the living room, and the computer was also available to use in guest mode, with a printer and a great stereo system attached. Wifi connection was stable and fast. Sometimes we could hear the neighbours through the thin walls while using normal volume, but that was not disturbing at all. The subway station was only a few steps away from the apartment, so it was absolutely easy to get on a train.
To sum up, I think Shawn's apartment is a great choice, and has my highest recommendation.
