Hi Ingrid,
Consider an alternative. If you want a pretty little Ligurian seaside place with colorful buildings, take a look at Camogli. Easy to get there by train and there is an elevator from the train station down to the boardwalk where there are bakeries, restaurants, and shops. I do not know about hotels because we stay in apartments. Instead of walking on crowded trails, you can take a scenic boat ride to the nearby 10th century Abbazia di San Fruttuoso --- it's nice to explore.
I'm pretty sure there are beaches and for sure a little harbor full of boats. Easy to take a train into Genoa and to other places along the coast. There's a direct train to the Cinque Terre that takes an hour and a bit, so very doable as a day trip. Camogli will not be anywhere near as full of daytrippers as the Cinque Terre.
When we stayed in Camogli, I was hobbling around with a severe foot injury, and have a good memory of what it's like to walk around there!
