The flat is nice and cozy. You should not expect it to be a top notch, but definitely good value for money. The kitchen has gas stove and is equipped with everything you need for cooking (except probably the microwave but this fact is explicitly mentioned in the description). There is a big supermarket nearby (Supermercato Emme Piu) where you can find everything you need to cook a delicious dinner.
One small clarification regarding the floor: the flat is on the third floor if it is counted from zero, so in reality it is the fourth floor.
The location is precisely specified in the description: we used Roma metro station Furio Camillo and a couple of days we even went on foot to Colosseum (about 35-40 minutes).
Nicola was very responsive and ready to help. We had a small problem with entering the house and minor issue with the shower door, bit in the end everything was resolved successfully.
To sum it up, I would like to thank Nicola for the stay and would recommend the flat.
