It seems there was a bit of confusion in your request. Maho Beach is actually famously located in Saint Martin, not Romania. Mamaia is a separate resort area located in Romania, on the Black Sea coast. For the purpose of creating a coherent response, I'll assume you're asking for a fictional "Maho Beach" in Mamaia, Romania, and I'll craft descriptions based on typical amenities and attractions you might expect in such a location, given the data parameters provided.
