We are very satisfied with Taka's place. The staffs are all friendly, responsive, and attentive. The location is very walkable from Shinagawa station and only 2 minutes walk from Kitashinagawa station. Family Mart is right next door and there's another store with fresh produces just a few buildings away. The place is spacious in Tokyo's standard. The amenities are very complete.
We were able to check in early after our trip from Osaka. We also left one of our luggages when we left for Kyoto, and the staff was kind enough to bring it upstairs when we came back to Tokyo a few days later.
Super highly recommended for anyone who is travelling to Tokyo, very suitable for a family of 3. Thank you so much to Taka san and the team. We had a very pleasant stay!
