I stayed at this studio for just over a week. Check in was easy enough, Zhenya had said he would meet me at the apartment but then had to leave early so left the key for pick up at Liverpool St, which all went fine. Zhenya's communication and responsiveness was always good.
The studio, however, was not clean, very cluttered with boxes and instruments, and didn't feel like it was set up to accommodate guests. Lots of little flies everywhere, many surfaces dirty and with random stuff all over them, and some really gross stuff in the bathroom. Studio doesn't smell great, is dark and damp and not at all airy - only one window which you can crack a couple of inches. I'm generally not fussy, but the studio seemed like it had had at best a cursory wipedown before I arrived and felt like the owner had just popped out for 5 minutes. It's indicative that there is no cleaning fee for this place. Sheets were clean and bed was comfy, at least. The kitchen isn't very usable because there is no space to prep anything - you could boil pasta or warm something in the oven but that's about it. No cupboard space available.
Location is great, lots of bars and restaurants and very close to central London. There is quite a lot of noise from the street (the studio window is street level and people often congregate immediately outside), the bar opposite closes at midnight so it's quiet fairly soon after that - street noise was a long way from the worst thing about the place.
I think the whole place would be ok if it was like £50 for the night but at the current rate it is absurdly overpriced - you can definitely do better and I would really not recommend this place, and would strongly advise against a stay of more than 1-2 nights if you really need to be in the area. Hopefully I'll be the last mug to pay as much as I did for a really not very pleasant stay.
