I am always really cautious about posting a less than positive review. However, out of all the AirBnBs I've stayed in around the world, marina's apartment has been the poorest one I've stayed in.
As a host, Marina is superb. She is attentive and responsive. we had some major issues arriving in San Martino and were unable to arrive before the check in cutoff. Without any fuss whatsoever, Marina helpfully arranged alternative accommodation. When we arrived, the weather was still cold. As the building's central heating had been switched off, marina arranged for 3 portable electric heaters to be available - and they were needed. unfortunately, they resulted in overloading the power circuits at just after 10pm each evening. The 2nd night, we had no power until the circuits were reset externally the following morning. I query whether the place should be rented out in spring without central heating. Its not really fit for occupation.
Nevertheless, we had a lovely time in San Martino. Its a fantastic destination.
