Yu's place was very stylish and neat. A short ~8 min walk from Meguro station, the location is also impressive, especially during cherry blossom season. The bed is pretty comfortable, and the bathroom is excellent! Though the apartment is atop a karaoke studio of some sort, I never found the noise to be bothersome. The wifi has a limited amount of data for use, but unless you need to do heavy work on a computer or will be an instagram power user, it should be sufficient.
However, I would like to add this disclaimer: this listing is not going to be comfortable for anyone with a feather allergy. The residual dust/particles from the down comforter and pillows caused severe allergic reactions for me (e.g., constant sneezing, congestion, redness, itchiness) – and made it unbearable to hang around in the room. I only really came to the room to sleep, and couldn't really get a good sleep in throughout my stay. IF YOU AREN'T ALLERGIC TO FEATHERS, you should have no issues – I just want to include this tidbit for others in the same predicament as me going forward.
