This was my sixth stay in Rome and definitely the best lodging by far. It was a perfect experience:
1. The hosts - Maurizio & Fabio are friendly, helpful, always there when you need them and just very nice people. Not only was the welcome warm, they were extermely helpful to an extent quite beyond the necessary.
2. The appartment is spacious and well designed. The two terraces are just spectacular and we were sorry we couldn't spend more time there. The facilities are in perfect shape and the appartement boasts all things you might need through a stay in Rome. It is quiet, too, and the beds were quite comfortable.
3. The location: WOW! Literally three minutes to Piazza Navone and five to Pantheon. It's a cute little lane and therefore despite the location quite peaceful. Donwstairs is a bike rental, and there is Carrefour 400 meters away. A deli shop (expensive but good) for wine, cheese and salami is about 200 meters away. Next door to it you can buy dolci ... And that's not all by far.
In short: we really enjoyed our stay and honestly recommend this appartement and its hosts.
