Really clean lovely flat, which looks just like the photos. Comfy bed, good wifi, quite a large room, very nice bathroom, incredibly good value. Next to quite a busy main road but not noisy at all inside. Was a bit worried about the area before booking but I had no problems walking around the area in the evenings, and the flat is very close to the DLR - very useful for getting to the City (about 15min). It's probably useful to know that there's not very many supermarkets close by.
I only met Siwen once (during check-in) in my 3 night stay, but she was really lovely and welcoming. Didn't meet Luke at all but this was probably because I was out quite a lot. They have a very sweet cat who is around quite a bit.
All in all, a great first experience with Airbnb, and I would definitely stay again!
