Residenza Domiziano are serviced apartments with proffesional staff and clean rooms. Rooms are standard hotel rooms with a bathroom. What I liked the best is the location, just 5 minues walk from the Fontana di Trevi and Spanish steps. Also, in front of the accommodation is the nice square with an entrance to a metro station. Also, whole neighborhood is filled with bars and restaurants, so you have a lot of options for lunch, dinner, cocktails etc. Great option for those looking to explore Roman cuisine. I recommend to try restaurants in the streets bellow Spanish steps. Take care that the reception is open till 7 PM and after that time you can use access code to enter the building.
