The host was excellent. He took time to greet us upon check-in, show the map of the places we should visit, organise a Podgorica airport transfer, take us to restaurants (we arrived late at night, so he wanted to make sure where we can find places to eat), and also he let us leave our luggage (in fact, a late check-out at no additional cost, given it's quiet being winter) until we were ready to leave in the afternoon for our flights.
All these immensely helped our visit in Kotor, and made things a lot easier for us.
Really appreciate everything!!
Kotor is a beautiful town, and the Montenegro locals were so helpful and friendly. (To be honest, quite a comparison to our experience in Croatia, in a pleasant way!)
