We booked this appartment as a group of 6 people. 5 minutes away from Termini station, a central point with connections to all city and the airport including metro,bus,airport bus,taxis to go all over the city. There are plenty of pizza restaurants,gelaterias,cafeterias and supermarkets to facilitate some needs for food and drink. Of course if you want to enjoy Rome you should go further to the center for more sightseing,eating,shopping and entertainment, which is less than 20 min using public transport. Returning back from trastevere would cost you around 10 euros by taxi which is fair enough if you share it with 4 people.
The appartment itself has 1 bedroom with 2 single beds (which you can merge them if you are couple),1 double bed and a double sofa bed in the living room convenient as well for 2 people. Kitchen has all facilities so that you can cook if you want. I would recommend a replacement for the espresso machine in the kitchen as it was some kind of dirty and broken.
Bathroom was fine and there is no problem with hot water because it has a boiler (so 24h hot water). Again here a better mop is needed in order to clean the bathroom because there is no hole on the floor for the water to go off.
Overall we enjoyed our stay in Rome using this appartment because it was a good value for money and I would recommend to other people.
