The apartment is comfortable and had everything we might need for our stay. We were missing dishwasher detergent, however, and the nearest Tesco only had a 48-count large bag so we just washed dishes by hand. But not a big deal. Also wish we had a couple more towels as we were there for six nights. We ended up washing hand towels and wash cloths in the machine once during our stay, so it was fine.
The apartment is very close to the underground and bus, which made getting around the city very easy. Walking distance to St. Paul's Cathedral and Tate Modern. It is in a quiet area with no night life or restaurants right nearby, but that didn't bother us. We did walk to Oriole Bar, which was wonderful! But other than that, we mostly took public transportation out at night.
Janet is very quick to respond to questions and I appreciated her communication throughout.
