A perfectly acceptable place to spend a night as you are passing through. Though I can't imagine anyone is vacationing with Windsor Locks as their final destination, if there is more to this place than I know and that is your plan, then I would probably not think this would be your best choice.
Hallways could use a deep cleaning to get rid of a not-so-great smell, the lobby is just very basic and could be better maintained, and the rooms are definitely dated.
But the rooms are generally clean, sheets are clean and in good condition (and are free of the odor from the hallway), check-in is easy, the location is prime for the airport, and it's about the cheapest you're going to find in the area.
All in all, if money isn't a factor and you want a bit of luxury, you can do better but if you want to minimize costs and don't mind minimal accommodations and some imperfections, this place is perfectly acceptable!
