Absolute fabulous location!! Everything is walking distance. To the left you walk out to the Vatican City in 10-15 min. To the north you can walk in less than 5 min to Piazza Navona and you can walk further through to Piazza de Popoli, Villa Borghese and Spanisch Stairs etc. To the right you walk in 10-15 min to Vittorio Emanuel Monument. From there you're very close by Forum Romanum and the Colosseum. (Wear you're comfy shoes...)
The appartment is great, very cosy, comfortable beds and bathrooms. Great hotel room feel, everything available. Well suited for a couple visiting with another couple, just be aware that the downstairs bedroom doesn't have a door. The upstairs one though, has a double door, so when closed everybody has their privacy.
Barbara warmly welcomed us and gave us a couple of good tips where to eat in the neighbourhood. Try them out!
We all will recommend this place to anyone visiting Rome!
P.s.: We loved Cul de Sac. You just have to be patient because there was a line (although we got us a number and went for a drink around the corner).
