The flat/room was very well. Everything was clean, good air condition, a modern bathroom and a mini fridge in the closet. Only the "kitchen" can be improved. There is no good kitchen equipment to prepare any real food. There is no pot, pan or sharp knife. It is sufficient to prepare some fruits or breakfast but not to cook or fry anything. Otherwise, everything was perfect.
The location is excellent. We explored the entire city on foot and never rely on public transport. 15 min. to Trevi fountain and around 30min to Colosseum. During the night it's very quiet as well and you feel safe all the time.
We enjoyed the time in Rome very much :)
