I have an apartment on the Fort Noks complex which is about 3km's north of Sveti Vlas on the Bulgarian Black Sea coast.
The apartment is front line, in other words, there is nothing between the apartment and the Black Sea.
The apartment is a studio apartment but it will sleep five! The beds are two double sofa beds and one single chair bed.
Having said that, I think a family of four would be the maximum number of people for residence.
There is a large shower room and kitchen which benefits from a full size electric cooker, refridgerator, microwave and all of the usual kitchen items.
The complex has six swimming pools, restaurants, beauty salon, bike hire and various other ammeneties.
There are many photographs on my website and I have a Face Book page also with photographs.
