we stayed as a group of 3 for 3 nights at Arietta. It is a convenient 5-7 min walk from Gotanda station, which is on the Yamanote line, only 2 stops from Shinagawa which is a major transport hub. There are restaurants, shops, and a 7/11 near by. Our room feels a little small for 3, but it is very clean, and supplies were well stocked. Staff was helpful and polite. There is continental breakfast in the morning, nothing fancy but has good coffee and croissants. Excellent price for a convenient location in Tokyo.
