Smile Hotel Tokyo Nihonbashi was a great budget hotel for me and my partners needs. We wanted to save on hotels because we were spending most of our time out the hotel, exploring. The bed fit both of us and was perfectly fine, there was AC and the option to open the window which i enjoyed and didn't have the option of at our previous 3 hotels. The location is very convenient for hopping on multiple subway lines and there were many convenience stores around. Because the location is central I believe we heard more emergency vehicles than any other stay during our trip, it didn't wake us up, but if you are a light sleeper that is something to consider. The hotel is a bit aged, which didn't take away any amenities, but you can see a number of scuffs on the wall from previous inhabitants. They also don't use keycards, but a physical key on a hotel key chain. I would not say that the hotel is dirty, however when we were packing up, I did a thorough inspection to make sure we didn't leave anything behind and there was a good amount of trash/dropped items and dust between the built-in desk edge and the wall, I understand that it is a very difficult spot to clean and retrieve things, but it wasn't the best sight. There was also a faint smell of smoke in our smoke-free room, but my asthmatic partner did not feel uncomfortable in it, they did notice it though. Overall a great budget stay, nothing fancy, but cheap, clean, and comfortable!
