It’s all about the deck and the location.
The rooftop deck is great. The view as shown on the listing is pretty accurate. It is the street below and the mountains behind the town. Still the deck is large and a great place to relax.
The location is steps from the ferry port, literally about a minute walk. Be sure to go into the streets behind the apartment. The windy, narrow old streets are full of character. There is a traditional baker hidden in an alley about a two minute walk away. The waterfront restaurants are right around the corner. All services you need - shops, rent-a-car, ferry tickets - are right beside the apartment.
The rest of the living spaces are good but the deck is the main selling feature.
There are lots of steps so definitely not for any with restricted mobility. The second bedroom has no closet or dressers and is a bit smaller. Fine for kids for a few days but wouldn’t be ideal for two couples.
