We stayed here for 4 nights in August and had an amazing time. The apartment had everything we needed to stay self catering with full kichen, outdoor terrace with BBQ with an extra balcony looking over the bay!
The host was so accommodating and did so much to help us with our questions and even let us stay late so we could make use of our last day.
If you are looking for a relaxing stay in kolocep then I would definitely recommend this apartment. You can either stay and explore the island or use it as base to visit the other islands/Dubrovnik.
