We stayed at Nathalie appartment 6 days (4 people - 2 adults and 2 kids). I can only say good words about Nathalie: she met us warmly near the door, explained everything about the flat and nearby location and was always on phone in case I had questions.

The location is very good: quite close to main attractions but not in a busy/touristy street. (10 mins walk to piazza Venezia, 15-20 mins to Colosseo, 20 mins to Pantheon and 5 minutes to Cavour metro or via Nazionale where lots of bus are passing + you can have nice shopping) Termini is not so far, but it's better to take a taxi to get to the flat if you have heavy luggage since it is not very convinient to walk uphill and downhill around 1 km.

The flat has 2 rooms: living room with a double-bed on a "second floor" is very quiet and the noise from the street is not coming there. It was good for kids.
The second room is a little bit noisy till midnight due to the restaurant in front of the house. But at night you can sleep there with no problem.
Kitchen is big enough and equipped with everything that is needed for cooking. (Although I used to cook mainly smth quick for breakfast) You can eat in living room or outside on the terrace.
Bathroom is spacious for Europe and everything was working.

WIFI connection was reliable and fast enough. I used washing machine – it is working well, but the clothes were rather wet after – so it tooks around 1 full day to dry it – please take into account.

I would strongly recommend this apartmenr for 2-4 people (family with kids pr 2 couples). Thank you Nathalie!
