The hotel is listed as being in Ornos Bay, but it is actually located in Costa Illios, about a 15 minute drive from the center of Mykonos town. This wouldn't necessarily be an issue except taxi service is difficult to access when you're outside the center. We frequently waited 30 - 60 minutes for a taxi to town while the staff at Sea View diligently called on our behalf. We were told upon arrival about the limited availability of taxis and that a rental (car, ATV, or moto) was highly recommended, but we hadn't planned on renting and preferred not to. Therefore, we were at the mercy of the taxi availability (our choice). We did walk to Ornos Beach one day, a 20 minute walk with some hills, so could be difficult for some, though we were okay as we could jump in the ocean or the pool on either end of our trip. We generally spent our days at the pool or beach and took one trip to town at night, so ultimately relying on taxis worked out for us. If you plan to go out more frequently than that, I would definitely plan on renting something. We never had a problem getting a taxi from the center back to the apartment, by the way.
The Sea View Apartments were practically brand new with gorgeous views of Ornos Bay. Our room had a balcony that overlooked the infinity pool and pool bar and beyond that the boats moored in Ornos Bay. The staff were incredibly helpful and attentive, calling taxis for us and in some cases transporting us themselves when taxis were unavailable. The rooms were a bit noisy at times, but otherwise we slept comfortably. Above all, Igor and his staff were very helpful and made up for any challenges we faced in transportation.
