A very nice experience overall, mainly due to the perfect location of the flat to discover all touristic places in center of Rome. However, if you are looking to rent a flat from locals, who will recommend their favorite restaurant and leave little attentions for you in the fridge; this is not the place. The flat seems to be rented by a professional company (no Alex and Luna around) hence a pretty impersonal and not so friendly communication, a quite complicated entrance procedure (we had contradictory info about arrival time and even though I mentioned I was 6 months pregnant and kindly asked to just leave a bag, it was all a bit complicated).
Appart from that, the flat is very nicely decorated and equiped, topically Roman. And the guy who gave us the keys was very nice, funny and made us forget the little wait in the street at the arrival :)
