I loved my stay at Luca's apartment. He was extremely helpful during our entire stay (even though we didn't need much) and helped arrange airport transfers for us. The apartment itself was simple, clean and in a great location. The best part about it is hands down the huge terrace - just having a little bit of outdoor space in a chaotic city is a huge plus! Note it is indeed a walk up to the top floor. This was no problem for us but if you have a lot of luggage or limited mobility I could see it posing a problem.
