This flat is great value for your money. I spent a little over a week here with my sis and we both enjoyed it. The flat: it's clean, modern, and just all around nice. The only issue the bed might be a little hard for some but that's about it.
The neighbourhood: is lively but we found it was the perfect amount of noise for us. There was always something fun to see, interesting people to watch, and there were tons of shops/stores around. The apartment is right on top of a Tesco so we didn't have to walk too far for groceries plus it helped us cook more. As two single women we didn't feel unsafe at any time, even when walking back late-ish (11/12) at night.
Transport: is pretty close by. Once you figure out where the bus stops are, you're pretty much set. The tube is about a 10-15 min walk away.
Bonus: Em has netfilx!! He also checks in and answers any questions promptly. Amazing host!
