This was just what I was looking for--a great long-stay option with a kitchen and good transportation options close by. The kitchenette had a sink, fridge, microwave, cooktop, and a dishwasher. And there was air con, which was much-needed since June 2022 was brutally hot and A/C in London is hard to come by. There are also laundry facilities on site (in the main bldg) which was helpful. It is located right next to Deptford Bridge DLR station (and close to Deptford and New Cross Train stations) and there was a bus stop that was right out front that allowed me to get to central London easily. There are a number of small grocery stores close by too (Co-Op, Tesco Express, Asda), but large supermarkets are pretty close via the bus, and there are a lots of shops just a couple of DLR stops away at Greenwich or Canary Wharf (also a lot of restaurants).
I felt really safe and it was very quiet, even though it was close to a busy road and to a light rail station. The staff was friendly and helpful; I mostly wanted to be left to my own devices, and they respected that. When I needed something, they provided it. The only slightly annoying thing was that the primary way to interact is via a Whatsapp group, and I am not a smart phone user (yes, there are still a few of us). For most people, I imagine this would not be a problem (and it wasn't much of an issue for me either). I would definitely stay again. It was exactly what I needed when I needed it.
