Overall, we had a great time in Mykonos. It was a beautiful island with great food, beaches, restaurants, bars, etc. The house itself is great. Plenty of space and an incredible view/pool.
We were warned to be careful about break ins, and we got lax. On our last day in Greece, we missed the lock on the window above the kitchen sink and we had a break in. We could have prevented the break in if we had been more vigilant, and we messed up turning on the security system. The house is set up to prevent such things from happening, but it definitely put a damper on things. We also didn't appreciate the way the management handled it. Basically telling us we had been stupid, about 15 minutes after it having all our belongings thrown everywhere and stolen by an intruder in the home we had to sleep in that night.
Lastly, bring bug spray. We got absolutely eaten alive. All six guests left with no less than 30 bug bites. Personally, I believe I have closer to 50. Most of them were mosquito bites while sleeping, but we are not sure they were all from mosquitoes or other bugs. We tried to keep all windows and doors closed the last 2 days, but it didn't really help. Plus, no one wants to be boarded up in the house while vacationing in Greece.
