I can't recommend this place highly enough. The location is perfect, within walking distance of every major attraction (Colosseum was probably the furthest walk and that was maximum 20/25 minutes through some lovely cobbled streets) and 2 minutes walk from some great restaurants, bars and sights. The apartment itself is also excellent, it's spacious, nicely designed and spotless. There were only 2 of us staying there but there are 2 ensuite double rooms so you could easily fit four. Barbara and Fabio were so helpful too, they gave us some great tips for restaurants and the portable wifi they give you is a great help around Rome. In terms of location, quality, security, helpfulness and comfort, this place is an absolute bargain. Next time I'm back in Rome I'll certainly be staying here! Superb.
