Pros: The location is excellent. Close to three major tube lines and the Portobello market and Hyde Park are in a walking distance.
Cons: A few things were broken in the apartment; there was no light up on the loft where the bed is, which made it very difficult and dangerous to get up and down from there at night. I saw ceiling lights so I think the bulbs just need to be replaced.
One of the knobs for the kitchen stove was broken off. I didn't cook so didn't matter to me but for those of you who are planning to cook, maybe inquire if that got fixed before booking.
Two out of three windows in the room wouldn't stay open. I stayed in August and though the weather was actually chilly and rainy, a typical English summer, it felt extremely stuffy in the room especially when you're asleep as there is no window by the bed up on the loft.
