David made all the difference by being completely knowledgeable and prepared to answer any question and provide any resource - from the best local sushi restaurant at a particular price range to providing a wrench when we needed to fix something on my wheelchair. He was a font of information on the Tokyo train systems and the best place to find everything from a child's bicycle seat rain cover to over-the-counter medication at a good price. He was happy to run out to our lost cab when we first arrived to lead us to the correct narrow street (alley) where G-stays sits, and he was equally happy to escort us out to the main streets to point us to restaurants and stores, including a local supermarket when we had a special request. Of course G-stays had lots of umbrellas to take and use as needed - and when the supply was running low on a particularly wet day, David got one from his private stash for us to keep during our visit.
The room (a studio apartment) was compact - particularly the bathroom - but worked out well for the two of us. The balcony, with its drying racks and plastic slippers, was also helpful. The room was generally quiet, the elevator small but fine, and David and his crew offered bottled water and fresh towels on request. He also gave us a whole box of green tea bags to keep in the room when we said we liked it. We never used the one-burner stove, but did keep things in the small fridge. There were enough plates, cups, glasses, and cutlery for the few times we ate in the room, and the kitchen area had a sponge and dishwashing detergent handy.
G-stays worked for us because although I use a wheelchair outdoors, we had a compact, folding manual wheelchair with us - and my husband could fold it a bit to fit into the elevator and unfold it to get me up the one step at the entrance inside the apartment.
My husband and I are very grateful that David's place was our gateway to Japan.
