Rome is a great city to see and it's definitely a good idea to be there for at least a week if you have a time to do so. Location of the flat is great as it's right in the middle of the city so you can reach every single attraction by foot.
We've walked everywhere and the flat is located in a lively but quiet and safe area so there is nothing to worry about when you're back late at night.
Tommy is really nice and helpful. He was waiting for us on arrival with interesting guide to Rome and took us around the area so we were able to familiarize ourself with the nearby shops. He's easy to reach through the phone or email ( there is a wifi in the flat ) so in case of any questions or issues he's always there to help.
Flat is nice ( smaller then what the pictures are showing ) good and comfortable bed, tiny kitchen but to be honest equipped with all the things you'd need to cook for a couple and a bit rundown bathroom and shower that should be looked at.
There is a great antico rorno roscioli just around the corner great bread, sweets and pizza by meter the rest you'll have to discover by yourself. Remember to book all the tickets especially to main attractions online to avoid long queues and if you want to see di trevi fountain or colosseum do it late at night as they look spectacular and there is a lot less tourists around at that time so you can have it almost for yourself. There is so much to see in Rome so manage your time wisely.
All in all it was a great stay in a great city and we've had a really good time.
