Cleaning staff is only there until 1pm, so they do not have the ability to give you a late checkout even if you're willing to pay extra, unless the room you're in is vacant the following night.
After about 10pm everything closes down and it's dark and the staff are gone. Though I bet if you needed to arrive after 10pm to check in, and called ahead, they'd accomodate you.
It's in a residential neighborhood, so there aren't any other stores or restaurants in easy walking distance.
When I called from the Ostia metro station to ask them how to get a cab, they just sent someone to get me by car, for free. For 25 euro they also have a shuttle van to Fiumicino airport, at the time of your choice.
Hotel shares a building with a bar/pizzeria/cafe, the two business are run by brothers. Their father drives the shuttle. Everyone is welcoming and helpful and nice.
Free wifi with no login required.
Fridge in the room, good desk, and air conditioner.
They sell bus/metro tickets at the bar/pizzeria downstairs, which is very convenient. A stop for one bus route is two blocks away, and a stop for a few other bus routes is five blocks away.
