The curtains are ridiculous. They need three feet in front and a solid wall and door, then they would be workable.
The Japanese versions are exactly like that they are two feet longer than the avg sleeping person with a locking door from the inside plus individual heating and A.C. Controls quite comfortable for a mid day power nap or a simple overnight stay while partying late in a near by city via train. There is enough room for your bags at your feet so everything you included is locked inside safe snug and sound.
$700 per month works out to $23 per day that’s MUCH cheaper than any hotel or even hostel in SF. In Japan they have public bathhouses so a couple days in a pod while treking is no bigs. Nationwide gym memberships are cheap and every one of them has showers to be had.
When I was a second time grad student I used my teaching stipend to get a gym membership and just slept in my office in the futton I bought against the wall, closed locked office inside of digital key card research facility no one cared as we worked on research till 2 or 3 am anyways a lot of nights. The research labs had a kitchen for use by staff. Had a microwave, convection oven too. Pocketed the $2200 per month stipend. GF was also a researcher so she crashed with me on the regular same department same major. $4400 a month between the two of us and no rent or bills was plenty of walking cash we ate out a lot just bring left overs to the fridges and label it.
