do you usually take long term guests?
do you want to take long term guests?
do you have it priced such that it really would be a good reservation for you?
you have next to no rules - fix that in general but certainly before you take on a long term guest.
I personally wouldn't want to spend 10 weeks in that space with 4 other adults : one bath, not enough beds, limited kitchen, small living area...
are they coming with cars?
I personally have a university student who will be away for the summer for a co-op. Housing is always a challenge for these kids. He and his friends would be great residents for a space but many kids probably wouldn't. The key would be setting some really good ground rules and making sure you have the buy in of every single guest.
My ABB space would never work for a long term guest bc I make too much money from the short timers to ever be cost effective for a long term guest, but your setup might be different. Would your summer be better or worse if you didn't have to deal with checkins and change overs?
Good luck!
