Small but clean with everything you could need. I made a few of my own meals and did laundry without issue since everything was provided.
Location is great, especially for Tsukiji market or heading to the Ginza area by foot. However, there is street noise. If you are a light sleeper, the emergency vehicles may wake you. Bring some earplugs if you think it might be a problem.
As for check-in and communication, there was also someone to greet me and walk me through the process - so no issues there. Even if no one was there, the instructions provided were clear.
During my stay, I was even contacted for a time window where they could pick up trash and change out towels. That was great and definitely something I didn't expect and really appreciated!
I’d definitely recommend to solo traveler wanting to stay in that area. Just be sure to travel light, as the stairwell is narrow and the room is small, so it might be difficult to manage anything larger than a standard carry-on suitcase. But it was a great place to stay for my needs, would definitely look at staying again if I'm in the area.
