What a view from the balcony! Just wonderful. The roof deck is a must visit - with its hot tub, and different sitting areas. Seaside Villas is close to everything - easy to walk along the beach or on the main street to get to anything.
We went snorkeling one day, played/swam at the Split another day, rented bikes and went over to the north island, enjoyed swimming and feeding sting rays at Iguana Reef Inn one afternoon (really recommend for those with kids).
Communication with Heydi about the property was clear. We were met at the airport in Belize by someone with our name on a sign. It took quite a while for the taxi to come, but we made it in time for the ferry to Caye Caulker. Once there we again were met and brought the two blocks to the apartment.
There are only very basic provisions at the apartment, but there are supermarkets very close by, so it's easy to go out and shop for what you need. Seaside Villas is also close to restaurants, so eating out is easy too.
We found the apartment a little expensive for what it was, but you're paying for the view and location, which were wonderful.
