The location is fantastic, I'm definitely going to stay around there next time I visit London. There is a very nice cafe serving great coffee just a minute away, and lots of other Shoreditch gems withing a few minutes of walking. Alex was very responsive when I had questions. In terms of London prices, this is quite a good find.
The apartment definitely has seen some better days, which didn't bother me too much. The place is LOUD though, specifically at night. There are two night clubs, one right below the apartment, and one right in front of it on the other side of the street. My stay was during the work week and every night there was music blasting and 20-30 people chatting under my windows well past midnight. During the day it's fine and nobody's there, so I was able to work without any issues. Also, the options for light in the studio are either trendy blue light or really bright daytime light. In the evenings I ended up reading using my phone flashlight.
