We spent a very enjoyable 4 days at Santa Cecilia.
We got the bus there from BA (and later found out that we probably could have been dropped off right at the bottom of the estancia's drive.) The house (built in 1908) is handsome in lovely grounds and our room was comfortable and characterful with shuttered windows , a brass bed frame and antique furniture. The adjoining bathroom was a delight with gilt mirrors, tiled floor and chez long. The whole house smells deliciously of spicy wood and home baking.
We left several pounds heavier after being treated to 3 large meals a day (all produce from the estate), plus meriendas and iced tea that magically appeared throughout the day. We ate with other guests in the main hall at a large table, or, when we were the only guests left, on the candelit verandah which was very romantic.
We took several horse rides (no experience necessary - very gentle quiet horses) with one or more of the gauchos including an afternoon with the gauchos as they did real work, herding cattle for a weigh-in. This was a great way to see the beautiful estate.
We saw many birds of prey, owls, bats and a large cayman in the 'pond'. There are also several well cared for cute dogs who kept us company too.
There was nothing so nice as lounging on the verandah's hammock or rocking chair, or by one of the permanent fires indoors. Sylvia (the owner) was a warm but discreet hostess who gave us plenty of space but also made sure we were entertained. She had great ideas for riding routes and I'm sure she arranged specially for her son Diego, the estanica's business manager, to be present at one point to explain some of the running of the ranch in his excellent English.
Whilst there we also visited the nearby (30km or so) Jesuit ruins at San Ignacio where we had an excellent English speaking tour almost at closing time and then went back in for the new son et lumiere show which started on 1 August and if it is still on - go! It was quite magical.
We look back fondly on Santa Cecilia - Sylvia and her neice Marienna (visiting and helping out with the great food) made us very welcome indeed and were interesting company. As we had booked in advance and all meals and rides etc were included, no money changed hands whilst we were there, which added to the feeling of being a true 'guest'. We loved it.
