The Smile Hotel Asagaya was the first impression for my son and I, upon visiting Tokyo. The stay left a good impression. Though the rooms are small, the staff and accommodations are great. We enjoyed our time here.
A good hotel. Beds are decent enough for a short stay, cannot hear the trains or street noise, windows do a job of blocking out the sound. Vending machines for hydration on every floor, beer vending top floor, both inexpensive. Can get to everything you will need in the area for food, bars, shopping, etc. Would stay again.
