Hotel, motel and hostel are commonly thought of as a descending order of quality. What would a mostel be like?

I used to say Hostels and Mostels instead of Hotels and Motels

Hoy no he visto ni un Motel, ni un Hotel, ni un Hostal, ni un Hostel… Hoy he visto un Mostel.
¡Superad eso!

Today I have not seen a Motel, nor a Hotel, nor a Hostel, nor a Hostel ... Today I have seen a Mostel.

You may have Zero Hostel, Zero Hotel, or Zero Motel. ‘Mostel’ is not a word.
