My stay at Joanna's was great!
Joanna and her family are fabulous hosts, very open and welcoming! They are there if you have a question or need something, but not hovering or imposing to where one would feel uncomfortable at all.
The place is clean, the bed is comfy, and every amenity in their home is guest-oriented and well thought through. Love that in addition to your regular amenities, I had a trash can for recycling in my room, extra charging wires for electronics, electric kettle besides the regular coffee maker. The devil is in details and they got him by the tail, lol.
Also, the place itself is somewhat in the center of the island, so you have a comparatively easy drive to whatever the adventure your heart desires. Additionally, Joanna is a great resource. If you're not sure about what to include in your trip, she has a list of must-see places and trip suggestions.
I loved my stay at Joanna's, would book again without hesitation. :)
