We stayed in apartment 1: It was incredibly clean, well maintained, hot water in the shower, cold AC in the rooms, the host provided chairs for the beach, beach towels, and it was close to everything! It's a short walk to restaurants, bars, and bio bay tour meeting locations. Despite a lot of comments about the roosters on the island waking people up early, we barely heard them until we went outside (then it was wildly loud!). My only complaint, and it's trivial, is that the apartment, which had pots and pans, cooking utensils, plates, cups, glasses... it didn't have measuring cups or measuring spoons. The stay was fantastic. The host communicated really well, and when guests in another room accidentally locked them selves out of their room, someone was onsite quickly to assist them. I would definitely stay here again when visiting Esperanza!
