My stay at Rei's place lasted a month and went well. Only issue I had was that initially the shower water seemed to only have been cold water (no matter which way it was turned) and then a few days later it was only hot water. After messaging Rei about it, someone stopped by 2-3 days after our communication and from that evening onward the water temperature was more controllable.
Things to note: there is a portable electric cook top, but it doesn't get very hot so I would recommend testing it before going to the store to decide on meals.
Overall, I do recommend this studio, especially for those that only need a place for a couple weeks or less.
