I ended up deciding on staying in Tokyo for my late June/early July trip instead of going to Hokkaido, assuming tourists are allowed to enter by then. I booked the Akihabara Washington Hotel, right across of the Akihabara station. Tiny room, but only $47/ni and a great location. Has anyone used this hotel who can give an opinion on it? And if so, how was the WiFi at the hotel and was there a place to work from, desk or table?
