Can’t beat the location - Literally steps from the Colosseum and surroundings. Worth it for just having the center of Ancient Rome to yourself and not need public transport.
The unit itself has the necessities, basic furniture, and yes a tiny shower.
For being so central it is all very quiet except if the Irish pub downstairs is full. But it’s nice ambiance.
Two things to be aware of - the check in and door access when you arrive are all done by you, and the door access can be kind of tricky since you need a good 4G connection to trigger the lock and that can be hard to get. I am sure the managers can help you if you are stuck. Tiny elevator of that is an issue (but works well)
Also there are some sewer smells from the bathroom drains - they will bring you chlorine tabs if you prefer that odor.
Remember to carry your keys - you need to unlock it the grate door by key to leave, which can be a safety item to remember.
But the location is what you are after and it can’t be beat.
