Nice comfortable appartments in a good area, with vintage furniture, sculptures and modern equipment. Our seven-year twin girls felt themselves like princesses in a palace. :-) A subway station is just in a few minutes walk. Trevi fontain is about 15 minutes walk.
Dario, the host of the apartments, is a very nice person attentive to details. It was a bit cool in Rome those days, but the appartments were warmed before our arrival. The heating system is easily activated by one button. Thanks to Dario we were also informed about nearby restaurants and the best ice-creem :-)
