Summary: great choice that you will not regret.
Location: we spent some days in GeorgeTown before moving to this Farmer's Hill property. Among the two options, Ivan's property was our preferred. In town you have way more traffic, considerable noise from the on-going projects (even very early in the morning), and you are farer from the best beaches. This property is steps away from a beautiful, endless beach, and still w/in few minutes driving from the airport and several bars and restaurants. Also we found groceries at a close market to be less expensive than in GeorgeTown.
Home: it is clean, recently remodeled, with very good A/C and TVs on both floors. In the kitchen you will find modern small appliances and you even have a small laundry room.
The only concern I would have is about the beds. The house is reported to have two queens, but the smaller room has actually a full size bed. So as a consequence I would suggest for three adults (not four).
Host: Ivan is outstanding. Friendly, knowledgable about the Island and he knows literally all relevant people. He will help you in pretty much whatever you may need.
