The two most prominent features of Alessandro's apartment are (1) the host and (2) the location.
Before that, the apartment itself - large, super convenient, and has all the needed amenities, including a very convenient kitchen with a Nespresso machine and all other utilities needed for a long stay, a very good bed, and many fine touches such as hotel-level soap/shampoo/vanity sets/shaving sets/toothbrushes/whatever-you-have-forgotten-and-could-ever-need. Convenient and professional!
But, back to the main features:
The hosting itself is perfect - Alessandro is always available and helping, and gives a very thorough and helpful introduction to Rome, with a plethora of explanations and recommendations, which were really helpful, especially Welcome To Rome experience, the LABotegga pasta place and the Samt'Eustachio cafe. Very professional!
Regarding the location - we couldn't wish for a better one.
From this place, you literally walk to all possible first-time tourist sites in Rome, maximum for 20 minutes. Maybe 25 if you go to gallery Borghese.
And for those arriving from Roma Termini, bus 64 brings you door to door in under 20 minutes.
Highly recommended, and hope to stay there again!
