I stayed with Lucy & her family for 4 nights & I can really recommend it. The location is great, especially if you want to see the eastern parts of the town like Tower Bridge. It's less than half an hour walk there & less than 10 min to the next tube station. Lucy had no problem with my late check-in & answered messages very quickly. The room is small but totally fine for 1 person & really nicely decorated with a little personalised welcoming sign, a small fridge, water, tea, cookies & chocolates. She prepares breakfast every morning, even if she has to leave for work. She didn't see much of me because I was out late every day exploring the city, so there wasn't much direct interaction. But the few times I talked with her or her family, everyone was very nice & helpful without being too pushy. Thanks for letting me stay :)
