Business traveler; only speaks English; 6-night stay
I flew into HND: took the Keikyu (KK) line, transfered to the Minatomirai (MM) line at Yokohama Station, and then got off at Bashamichi Station (leave thru Exit #3). There are options where you don't transfer but this route has the least amount of walking. I got a bit turned around because I didn't know which station exit to take (turns out not #5) and couldn't find the hotel. I called the reception desk and they sent someone out to find me about a block away and walk with me to check-in.
I stayed in a single room. Was small but the bathroom is generous. The nightstand had both a standard 2-prong outlet and a usb slot; there is a 3-prong outlet behind the mini-fridge if you're desperate. Every room has a usb charging cable (lightning, usb-c, micro-usb). The window had black-out curtains. The mattress was on the firm side and the pillows were very squishy. The wifi was fast enough for netflix. A/C works great.
If you put out the "do not clean" sign in the morning (other options are "full-clean" or "eco-clean"), you will get a bag on your doorknob that has fresh towels, a bottle of water, and another new toiletry kit. I stayed 6-nights and only used the "eco-clean" once so I accummulated a lot of towels that I didn't need. The breakfast buffet was very good; it had a wide variety of food (fish, dumplings, miso soup, eggs, etc.) plus a small set of "western breakfast" staples like cereal and yogurt.
