Found this place after a long search for my extended stay in Tokyo and I’m glad I went with Alt Stay. The building seems to be fairly new and the unit itself was spacious, clean and had all the expected amenities.
The host was also very responsive to my inquiries. All questions were answered quickly and with fine details.
Location was great as well. Centrally located in Shinjuku but without the usual crowd. It’s in a quieter residential area of the city but with excellent access to train stations and restaurants nearby.
I highly recommend this place and look forward in returning again.
