Nice and friendly host with good communication. They gave a lot of details and helpful instructions (including how to get here from the airport). Great location if you have a long layover at Haneda or just need to be near the airport in general. Very safe, clean and spacious room with a comfortable bed. Room has washing machine as well! Also close to a combini in case you need anything.
Thank you so much Nanbu-san, 10/10!
