The place is in general clean, easy to reach, and very convenient for daily use regarding the interior and the proximity to subways and shops.
One thing, which I cannot emphasize enough as it is not marked in the room description, is that it is VERY NOISY!!!
It’s just a fact, so if you don’t care about traffic noise that goes around literally 24 hours a day (the room faces a major highway of Tokyo with the highway entrance right in front of the balcony, and it is 10 meters away from a major crossing in the center of the city), and if you are ok with earplugs (they prepare those for you), then maybe it’s not an issue.
I would say that the noise is beyond expectations when you hear people say “the room is a bit noisy”. You cannot really open the balcony window. Personally I felt I were sleeping outside in the road sometimes when it’s already after midnight.
Other than this issue, it is quite a comfortable room with all you need for an extended period of stay. I asked for a rice cooker when I realized I had to stay longer and they very generously provided it, and they also refilled the amenities upon request. It would be good if there is cleaning tools in the room, since it can be quite dusty when you open the window from time to time. I tried to get an extra cleaning during my 7 weeks of stay, but they didn’t provide or say no even after I reminded them. The communication is not as personal as you expect from an Airbnb host, but it’s understandable as they are managing not just this one room.
But again, it’s not a five star hotel that I am paying for. And with the excellent location and interior I suppose this place is more than good enough for your money. Again, the only thing I would hope I had known before reserving it is an accurate description of the noise level.
