Spent one night in Suigetsu with my boyfriend for my birthday. I've never been there and we were charmed when we arrived. The room is convenient to the parking lot and office, but still removed and quiet. Cute bed and we loved the Japanese decor/feel down to the movie selections (we chose Shall We Dance, the original Japanese version -- a must see.)
We soaked in the communal tub, which is clothing optional in the evenings. The soak was nice, relaxing, and not at all creepy though I was the only woman in the tub. The cold plunge and sauna were nice additions.
We enjoyed the room and the Japanese decor touches, but it turned out that the radiant floor heat made the room too warm to sleep in. The bed itself was uncomfortable (too soft and not enough support -- very un-Japanese) and we both slept fitfully which was a big disappointment. Also, the very nice, door-less shower leaked all over and we had to pile our towels on the floor between the toilet and the shower to prevent a puddle from forming in front of the toilet.
The next morning, my Thai massage hit the spot and we were off to the Plaza for our next evening since our late booking allowed us only one night here which was probably for the best since I need my sleep.
