Staying at Francine's was very good experience, the flat is located walking distance to Tower/Tower Bridge and tube connection to the centre is very good. Tube station is around 1 min walking distance. Bruno who was filling in for Francine was very nice and accommodating, he gave us good advice for sightseeing and helped is find the apartment. There are 3 rooms in total in the aparment, 2 of which are very nice, however one room (which was the one we got) was a lot smaller and less nice, when arranging the stay I would recommend to ask about which room you are getting! Overall, we would definitely go again, for the price this was the best we could find so close the centre.
