Hour, day or month for parking
For parking, the choice between hour, day and month is a choice of rate. It decides which price your budget is measured against, and it leaves in the results only spaces that have a price in that unit.
A space its host priced by the month only does not appear in an hourly search, even when it is free. It is not an expensive space; it is a space that is not let by the hour.
You can mark availability for today or tomorrow, or pick a date. The check is made over the whole day, so as not to hide a space that is free for part of it.
The host can set a minimum and a maximum parking length. When the search carries a time window, spaces whose limits do not fit that window drop out of the results. The parking length itself is chosen on the booking screen, not in the search.
