I only stayed in Symi for a couple of days, so if you are planning a trip definitely consider staying longer. The apartment is delightful with a gorgeous view over the harbour and a bigger balcony that’s over the side street. You are perfectly located for some of the best restaurants, Pantelis is an absolute must - the feta and honey pastries are incredible. You can easily get to St Nicholas beach (walk is possible but there’s an hrly bus for 2euro) or about 30 odd minutes (plus all the time you take stopping to take photos) in the other direction there is a beach called Paralia. There are also boats right outside that will take you to other beaches around the island you can’t reach by foot. Wherever you go, the apartment is just there when you arrive back in the port which is ideal for popping back quickly to get changes/have a rest before going out to dinner. There’s also a cute little kitchen if you want to stay in and cook some of the incredible fresh fish you can buy - it has everything you need, or just a kettle if you want a cup of tea/coffee.
Next time I’ll have to stay longer so i can actually spend more time in the apartment.
