We stayed for 5 days in this location. We were 6 people, all friends in our twenties. The place was spacious and mostly clean, some dust here and there but nothing major.
The beds on wheels were a surprise, to be sure, but quite fun, especially to rotate your friend in the middle of the night in their sleep. My back can still feel the imprint of the bed's springs but it wasn't too bad of an experience for me, despite severe back issues.
There were 2 bathrooms for us 6 to share, one in the hallway and one was in the bedroom with 2 single beds. One of them will allow you to experiment what it would be to jump in an active volcano with no way to turn it down. Indeed, to shower in the hallway bathroom, we stood outside the water flow as to not burn alive. The second shower was great and worked perfectly.
The living room and kitchen were both nice, clean and well equipped.
The neighborhood is decent with stores nearby, a McDonalds and a few restaurants to take-away food from. The train station (overground) is also a 5 minutes walk from the building, it'll be a few pounds each to reach Blackfriars (if you're 6, discount) to then take the tubes to wherever you wish to go. Only annoying side of the location was a lot of police cars rushing through the streets during the evenings and nights. We also came across a lovely dead fox on the way to the local Tesco. Good and fun memory for everyone.
TL:DR - If you're a big group of people then yes, this is a good location for you to stay in. Good value, clean, spacious, well equipped, near public transports and close to many stores and restaurants. There is also many windows in the living room, a balcony for the bedroom with 3 single beds and windows in the other bedrooms, allowing fresh air in the night to engulf you.
