We stayed at Stefano and Valerie´s apartement from 29.dec - 1st of Jan-16. The apartement is on the 4th floor in a building a stonethrow from Pantheon, but very quiet.
Stefano arranged for a driver to pick us up, and also booked a table at a beautiful restaurant next door on New Years Eve.
They deliver service equal a 5* hotel, and was on call 24/7.
The apartement is delicate and clean with 2 bathrooms, 1 bedroom and a sofabed in the livingroom. Supermarket, just around the corner.
They have written down excellent tips for restaurants, icecream Giolotti, the best coffee in Rome; Sant Eustachio. I am not a coffee lover, but their cappuccino is to die for.
Our stay was perfect, and when returning to Rome, this will be our nr.1 apartement.
