I’m a bit conflicted about writing this review, but want to leave it for others considering whether this apartment (or the many others in the complex) is right for you. On the plus side, it is a very good value for the location, just next to Hyde Park and Kensington Gardens. Billie and Max were also very communicative and friendly.
On the downside, I think the photos are a bit old. The place, including the common area of the building, is somewhat run down. Not dirty exactly, but slightly dingy. The walls are paper thin and we could hear the couple next door ad if they were in the room with us.
If you’re thinking of renting the apartment, I would recommend reading the host bio, which explains the layout of the place more clearly (30 studios owned by the same couple, in the same building, serviced by a third party). By my estimation, it’s one fairly large step up from a nice hostel, but I freely admit I may be overly picky. Judging by the many excellent reviews, I seem to be in the minority, so YMMV. I’d venture that if I were a traveling 20-something, this would have been perfect—if you’re older, maybe not so much.
