Mirko's place was absolutely perfect for us. Mirko was even better!
We flew into Rome on 10/5 and our worst fears were realized when our bags didn't appear (connection in Charlotte was late). We were taking the train to Florence so all we could do was give them the address to Mirko's place and hope for the best. Since we didn't have bags to lug, we decided to walk from the train station. Mirko was in constant contact (via Airbnb) regarding meeting us. We ended up getting a little lost, and finally, Mirko recognized me from my profile picture and rescued us down the block. He commented on how light we traveled (ha-ha). The apartment is somewhat hard to find (look for the Teahouse) and we were concerned about the luggage service finding it, and then having a safe place to leave the bags. Mirko, (after chuckling about us thinking they would be delivered the next day, Sunday) offered to let us give American Airlines his address to deliver the bags, along with his contact information. As predicted, the bags didn't show up until two later, Monday, when we were in Cinque Terre. No problem, Mirko met the baggage delivery man at his place, then schlepped both of them back to the apartment where they were waiting for us when we returned. Mirko also was great about calling a taxi for us when we needed it (we had become text buddies by then).
As for the apartment, it is just as pictured and was perfect for us. The kitchen and bath are small but met any and all needs we had. The bed was comfortable, and when we did need the air-conditioning it worked fine. The balcony was our main focus point, whether it was sitting there when we first arrived dealing with the airline, or breaking open some wine and enjoying the church bells.
It was also a nice respite from the throngs of Florence just around the corner on the Ponte Vecchio (get out early when you can). One of our best memories is of walking around the Santa Spirito neighborhood at night, getting a couple of pizzas to go at "Gusta Pizza" and then eating them on the steps by the Piazza Santa Spirito.
Wonderful experience and stay.
