I would go for a compromise and get a "wheel-on" smart trainer like the Wahoo Kicker Snap. Five minutes to install or remove the bike from the trainer and it's in a ready to ride state, small footprint when not used, plus these are the lowest cost smart trainers. The cons are; noisier than more expensive trainers, puts hard miles on the rear tire, and they generally can't deliver the maximum type of resistance - the Snap's simulation tops out at a 12% grade.
