Firstly, the room is smaller than it looks in the photos. It's comfortable for single traveler, okay for two. But for a family of three like mine with a small kid, it is a bit cramped. We do not even have enough surface to put things like wallets and watches. Secondly, my family stayed for six nights and the water heater wasn't working from the moment we checked in till we checked out. Our biggest disappointment is that the matter wasn't attended to immediately. Though the host informed us about the malfunction of water heater after we checked in at 9pm, and offered to pay us for public bath, it was highly inconvenient for us to travel out again and everyday to a public bath with a 4 year old. This is our first visit to Tokyo, we walked a lot every day and the last thing we want is cold shower every night after a long day. The host didn't show the urgency to fix the problem quickly or even update us if it's fixed. I asked twice, and the final answer is 'fixing is still in procedure'. Thirdly, the clothes drying rack was broken and I had to fix it myself to use it. Fourthly, about hygiene, the room is rather dusty. We suspect it's from the linen mostly, and the carpet smells of feet. The air-conditioner filter is also extremely dusty that we had to clean it ourselves to avoid coughing. I suppose these are the things that could be improved and looked into for an overall comfortable stay.
