Zuzana is a very nice and kind host. She may reply your chat a bit late so you have to spare time for waiting for her response. Overall, she is really helpful though. Her place is very cozy and clean. The location is very close to Maryland station and not far from Stratford station. Therefore, it is very convenience for going to central London. About safety, I considered it is quite ok even it is an East London where some ppl might think that it is less safer than west London area.
I recommend this place for any ppl who is looking for the place that is not only worthy price, but also pretty good location and nice host :)
