Chima's place is located in a nice area and has a great view of the Tower bridge and downtown London. Outside of the busy areas, but only a 5-10 minute walk to the closest Underground station. Very easy to get around. We didn't feel unsafe even when walking back at 11 PM.
Perfect place for 2 people; it's exactly as the listing shows. Chima was very responsive when we had any questions. I would definitely come back and stay here again.
