My 16 year old son and I stayed at Simon's apartment for three nights and everything was perfect! The location is very central to all the great sights. The neighborhood itself has a lot to offer with great restaurants within a two minute walk. The Metro station is easy to get to and very close. The Termini station is less than a five minute walk as well.
As for the apartment, it was very clean and very well supplied with everything we needed. The wifi was fast and worked great. The bed was very comfortable and the loft area was perfect for my son.
I would highly recommend staying at Simon's Suite to anyone traveling to Rome. Simon is also very fast with all communication and it was reassuring to deal with someone who is so professional.
I will definitely stay at Simon's Suite again if my travels take me to Rome.
