I stay at Horny Toad Guest House for five weeks at a time and love it. It's RIGHT on Simpson Bay. It's a very quiet property with only eight rooms: four up and four down. The bedroom is large; kitchen is well equipped; daily maid service. Lovely view from upstairs balcony; downstairs units open right onto the sand. Gated parking. Daily happy hours with innkeepers and other guests in the gazebo; attendance optional, of course, but it's delightful getting to know just a small handful of people. I checked and they have availability for about five weeks late March into April. You can check on line but it's probably best to call them and talk direct with innkeepers Debbie or Doug. I didn't find any availability in January or February; it's a desirable property and people book well in advance.
