First off, the location is terrific. It's very close to the metro, and it's on a small street next to a very busy one. The busy road has a great selection of shops. The apartment is very large and has the size of a large suite at a hotel. The bed is in a separate room to the living room, which is a nice touch. Having a laundry machine is excellent since you can pack fewer clothes. One note, there isn't a dryer, but there are racks for that. Laurence is very friendly and helpful. She responded very quickly to every question.
In terms of the negatives, I felt the bed was very hard and was more like a futon than a mattress. The other issue is the building is above a subway line, so you hear it constantly. It's not extremely loud, and nothing shakes, but it's definitely there day and night. If you're a light-sensitive sleeper, this might be an issue for you.
Overall this is a nice place and very convenient to get around, with an extremely friendly and helpful host.
