My room wasn't big, but I was nonetheless pleasantly surprised by it, given what I paid. The hotel has some style, though my room was a little characterless, and had no view of anything interesting out the window. The room had a simple desk, which was useful to me. I needed to do laundry, and they had a simple in-house laundromat which was cheap and easy to use. Everything was spotlessly clean. Two subway station were within about a seven-minute walk. Reception staff were friendly and polite. For one person, the room was fine. For two, though it had a double bed, it would have been a little cramped. And as I say, the room didn't have much character--pretty functional. But these are quibbles -- really, there wasn't anything to complain about. I would recommend it.
Small room even by japan standards.Staff were friendly.Room was clean.
Decent and clean hotel. Nothing special. The JAL City Haneda is much nicer and costs about the same.
