The pictures are not entirely representative of the room as it was when we visited - it seems to have been re-arranged since they were taken, and some objects may have been removed - I do not remember seeing the round table with the 2 chairs or the study desk although I could be mis-remembering, and the placement of the bed in the middle of the main room makes it feel smaller than it probably was when positioned as in the photos (although I can also understand how the previous location would have required people to climb over each other when getting in and bed, which would not have been a good setup). However it is still a nice place, with two separate rooms (with a lockable inner door) for those with privacy in mind. One minor point is that we couldn't figure out how to close the window blinds for the room, so my friend ended up being woken by the sun rather than in their own time. Also a lot of the drawers had a bunch of random objects in them, which I did see in another review but was still surprised by.
The main hallway (not pictured) seemed a little spooky when we first arrived, but we quickly got used to it and it wasn't actually too bad. The building does seem to be shared with 4 or 5 other private rooms, although I do not know how many were occupied and we did not find the other guests to be in any way disturbing - YMMV though. The shared kitchen is also around the corner at the end of the hallway, which we did not realise until halfway through our stay.
Location is okay, but could be better if you want to be in and around London a lot. We tended to take the train from Mile End station, which is a 15 minute walk away. You could also take a bus to Bethnal Green or other stations, but the one time we tried to do this we encountered a couple of buses already at max capacity before ending up walking to Mile End anyway. We did not explore much of the area surrounding the apartment as we mainly travelled to central London each day, so I cannot speak on things to do in the more immediate vicinity.
Ali was very responsive - it never took more than a couple of hours to receive a reply to my queries during our stay. At one point my friend managed to lock themself out of the inner room somehow, and Ali's partner visited twice to get the room unlocked that same evening.
