“Luca was the best!!! The trip was very nice but our guide made it even better. He was fun, intelligent, funny, and truly wanted us to have a great time. He even took photos for us at every destination. We drove to Lake Bled first. It was covered in snow and absolutely stunning. Since February is not the high season we had the castle to ourselves. We enjoyed cream cake at the restaurant with a view of the lake and then went to the island. The boat was €20 and was fun. We had 40 mins to explore the island and church. We skipped the church and just walked around.…”
