LOVE THIS PLACE! Ok, so it's very very unconventional. Heads up, it's a love hotel. The lobby isn't really a lobby, more of a discreet checkin for those looking to temporarily rent this place for a good time, not a long time. It smells like smoke, as you can smoke there. But my goodness. Once you get past that, the room is AMAZING! I've stayed everywhere in Tokyo from AirBnBs to the beautiful and expensive Cerulean Towers, to efficiency hotels to business hotels. Hotel D-Wave has been my favorite. It's the largest hotel room I've ever had. Completely private, marbled out, and is just insane. It had my own sauna, a giant whirlpool bathtub with aroma therapy supplies and bubbles and a tub TELEVISION! a shower, a separate toilet room (rare in Japan), and the room was MASSIVE! No closets but that's not an issue at all. There was a karaoke setup, tons of free current VOD movies, a 5.1 surround sound setup and you can blare it and nobody can hear you and you can't hear anyone else! Tons of high end ammenities and toiletries they restocked every day, and a fully stocked fridge where they charged you prices almost on par with the prices for drinks at 7-11. NO GOUGING! I love this place so much. I won't stay anywhere else. Also, location location! near 3 stations!
