This was such a wonderful stay! The location alone is perfect: it's a peaceful immediate neighborhood minutes' walk from a train station that connects to major lines, and so many delicious restaurants within an equally brief walk. You can hear the trains because you're so near the station, but I found it soothing since it's such a regular noise.
Riko herself was an excellent host: she was very friendly and quick to respond to messages, and she was waiting for me on check-in with information and recommendations for the local area. I made use of her local guidebook!
The room itself was very comfortable for a single person.
I would gladly stay here again! If you stay here, in addition to all the delicious food in the local area I highly recommend taking the time to enjoy the Meguro River promenade both during the day and at night. It's beautiful and there's more wildlife than you might expect in the city!
