I just had a 3 night stay in the studio. It was fine. Comfortable bed, generally clean, nice bathroom, nice towels etc. I would not say it was "luxury".
Location is good and it is quiet externally, no road noise etc but quite noisy internally - ie you hear people in the block coming and going, slamming doors etc and walking around upstairs.
I had some issues with the shower tray filling to fast and then leaking. I told the owner so hopefully it gets corrected.
It was good to have A/C but it made some very loud noises so I had to turn it off at night which was disappointing.
In summary, it was fine, nothing special but OK value.
