We stayed at this appartement with 6 people. This is possible because there also is a sleeping couch.
Service was great, when we arrived we where waited for and when one of the three airco would not turn on after shutting it off it was fixed the next day.
Also the location of this appartement is really good. Nearby the Coloseum and Termini, also supermarkets are less then 300m away.
The appartement was very neat with 2 bathrooms which where well taken care of.
All in all a good destination for a vacation in Rome!
