For me, the location was very good as I needed to be both in Woolwich and in London. (easy 20mins ride with the Elizabeth line)
The room was different from the pictures. It was spacious enough. The bed was not the most comfortable, but well enough. Only a little noise from the trains passing by. A LOT of noise from the other guests when they take the stairs (to entry or to shower/toilet) as well as use the shared kitchen. If I had one advice, earplugs would be it. That kitchen is OK, but could use a bit more plates/glasses.
Two toilets, which were clean. Shower kept changing between ice cold and terribly hot every five seconds.
Locks could be a bit more modern and safe.
All in all, I'd return for its location and price, but I'd hope for a better bed and a bit more quiet.
