We came from Germany by train (NightJet from Munich to Genova and onwards with regional train to Bogliasco), which went really well. We walked from the station to the house, which is up the hill (Lea warned us!), but doable if you are in good shape. So a great place if you want to come with public transport!
The place itself is phantastic, with a perfect view over the sea from the terrace. Lea is a great host, all questions were answered very quickly via WhatsApp, and she also accommodated our special wishes (like individual blankets, which is unusual in Italy ;-)). On the last day, we were allowed to stay longer, as the weather was bad, and we had to kill time until the NightTrain started - that was also very nice!
So it's definitely a recommendation if you want to a relaxed holiday in a nice environment, with enough opportunity to go walking or enjoy the beach!
