I stayed a few nights here for business and it was a perfect central location for everything I needed to do. Subway station entrances were very close by and you can see the trains from the hotel. Every once in a while I could hear them but it wasn't awful at all.
The room was nice and pretty roomy. The bathroom was spacious and had the multi-functional Toto commodes --lol.
The staff was very friendly and the concierges helped with opportunities for sight-seeing. They were kind enough to write detailed directions in both English and Japanese in case I got lost. I would highly recommend going to the fish market and exploring the Asakusa Kannon Temple which is a short subway ride away.
The restaurant/lounge offered a good variety of food and there were two options for breakfast--Asian and American. The American breakfast was tasty and service was efficient.
I would definitely stay again.
