It's a slightly steep place since it isn't really a hotel but more of a bed and breakfast, however, thanks to their excellent service and location, it is totally worth it.
Marco, Serena and their staff are all extremely helpful. Despite not being a luxury hotel, Deko is extremely comfortable and the owners go out of their way to help you with food, directions, tour bookings or anything else you may need. When we wanted to dine in, Marco personally went and got us food of our taste right to our room. Whoever is at the welcome desk is always ready to serve coffee and biscuits/toast at any time of the night or day, they even helped is with our taxis and luggage throughout our stay.
I travelled with my mother and we had an absolutely fantastic experience in terms of comfort, help and location.
The location is supreme.. Opposite the American Embassy, it is safe and central.
Whenever we travel to Rome, we are definitely staying at Deko again! Highly recommended.
