As many have noted, there is only positive to say about this apartment.
Location: It is perfectly located, only 10-15 minutes walk from the old town. Quite some steps to come up the hill but the view when you sit on that deck is all worth it. The views of the old town, Lokrum and the sea are simply spectacular.
We didn't have a car but were able to do everything we wanted to do by either taxi, bus or simply by walking.
Apartment: The apartment itself is perfect for two couples (you could fit 3 couples since there are three bedrooms) with two bathrooms. Well furnished, modern, clean, you have everything you need. The hot tub and deck area are a nice added value also for hot sunny days!
Service: Ivana is simply the best. She'll help you with transfers, excursions, restaurants, etc. She is quick to reply to emails/texts, she is always available to help with what you might need.
I wouldn't hesitate to recommend this apartment to anyone!!
