We stayed 3 nights. Very close to termini so it is a good base to explore Rome. A clean comfortable bed so if you are looking for somewhere to just crush, it's a good place to stay.
Things that you may want to know, though are that water of shower runs out after one person so you need to be quick to have shower or have shower at a different time. The pizza place that is supposed to provide breakfast doesn't open till later in the morning (checked at 8 and wasn't open then) so we have never had a chance to have breakfast there. Be aware that a fridge and a kettle are not available. It's not in the list of facility so it is my fault to make an assumption that they are there(in Australia, we almost always have access to them). The description was correct but I missed a cup of tea/coffee after a long day of exploring in the city and some of you may feel the same way.
All in all, an ok place to be for your quick stay in Rome.
