My wife and I stayed here for 4 nights in Mykonos and had a great time. The location was excellent, and almost everything in and around Mykonos Town was within walking distance, including an amazing selection of nearby restaurants. Fabrika Square, where you can catch buses to popular areas around the island and arrange for excursion pick-ups, is a short, 1 minute walk from the apartment.
The room itself was very clean, with daily room service to replace towels, sheets and toiletries. The bedding was especially comfortable and made for an easy night's rest. The streets in this area are unfortunately mapped incorrectly on Google Maps, but Alexia was quick to meet and bring us to where the apartment was located. If you are arriving by ferry, I highly recommend the SeaBus water taxi service from New Port to Old Port, where the apartment is just a short, 5 minute walk away. This is a much more affordable option than getting pick-up service, which will cost you about 40€.
We took the 7am ferry from Athens and had about 5 hours to kill before check-in. Luckily, there are plenty of breakfast eateries near the apartment where you can rest your bags and get some great food. A place called Nice & Easy was a great spot to grab drinks and hang out on the water prior to check-in.
Overall, our stay at AK Apartments was excellent and Alexia was a great host. I'd highly recommend this spot to anyone looking for a clean, comfortable home base in Mykonos Town with easy access to the islands main attractions.
