I stayed here while attending a conference at the convention centre - it was super convenient (10 min walk away) and really comfortable. The place is huge, way bigger than I'd expected, and it had everything I needed. It was pretty cold while I was visiting, but the heating system worked great. It did get a little noisy at night, particularly on Saturday night, but I usually sleep with a white noise machine so it didn't bother me. Great communication from the host, and very detailed instructions for how to check in. This place was way better than a hotel room, and it was under the government per diem rate :)
The only downside was that the living room floor/rug could have used a good vacuum. The kitchen and bathroom were very clean, however.
