Sayoko's place was amazing and so perfect for me and my fiance! Sayoko is a great host and was so sweet, and checked up on us to make sure we were doing okay! She also took our trash out when we forgot about it!! The place is very cute and feels very home-y and is perfect for 2 people. It is a 10 minute walk from JR Osaki, but the area is very nice and I felt very safe. It's maybe a 10-15 minute train ride from Shinjuku/Shibuya area, so it's close to the tourist destinations. If you're looking to stay in a quiet residential area in Tokyo, book this place!!
