You could not ask for a better location than this apartment. It's 10 minutes from the stations, near heaps of great chichetti bars and restaurants and an easy stroll to the "main" part of the island. Andrea's father Federico came and met us at the train station and helped carry our bags, which was much appreciated. As everyone else has said, the four flights of stairs is tiring but don't let this put you off. The beds are comfortable and the kitchen is fully stocked. Our only issue was problems with the heating and hot water. Federico came the next morning to help us and was able to put the heating on (thank you!) but the hot water remained unfixed -- the water tank is very small and takes ages to fill up, resulting in hot-cold showers and not great water pressure. There's also just one bathroom in the apartment, which also houses the only mirror and toilet, so this may be tricky if there's a lot of you. We managed to make it work though, and overall the stay was great.
