We didnt actually meet Florence but her roomate who took care of us while she was away. Communication with both was perfect.
The location of the apartment is amazing, litterally minutes away from Liverpool Street and Aldgate East stations which connect you to the rest of London. But our favorite thing was to just walk from a neighbourhood to another - and it was so great being in Zone 1 because we saved a lot on transportation.
The bedroom was small but comfortable, pictures are faithful to what you get. Florence's roomates are very nice and you can use all of the rooms (big living room, dining room and kitchen), so eventually you really have a lot of space.
The bathroom was below our standards (one shower head was broken, the other had very low pressure - consider this if you have thick hair!). I guess this is very common in London though, so I was not surprised.
The general state of the apartment was ok, not too clean nor abandoned either. The room was tidy and clean.

I recommand you to stay if you're looking for a good deal and a good location to enjoy london's daylife and nightlife !

Thank you Florence for having us :)
