The two of us have just checked out of La Casita and have been dropped off back in town by Lupe, the excellent taxi driver recommended to us during our stay. La Casita provided a lovely, countryside refuge after two weeks in Oaxaca City.
We enjoyed every minute of our time--cooking vegetables purchased at market in a lovely kitchen looking out on a small inner garden, eating in the warm outdoors surrounded by bird calls and fresh breezes, walking the mountain trails and the quiet roads into the villages, and meeting so many fascinating people who gave us the warmest of welcomes and made us feel immediately a part of a very vibrant community.
Wherever we looked at La Casita we were surrounded by beauty--the house itself is filled with examples of the various arts of Oaxaca and surrounded by well-kept gardens; at the pool, views stretch out across the valley to the distant mountains; and then there's always the Oaxacan sky.
If you do not have a car and are thinking of renting one, let me encourage you to think again. You are bound to enjoy being free of a vehicle. The walk to either of the nearby villages is very easy. There you will find good friendly greetings from the residents, very inexpensive internet service, stores to supply all your basic needs (including fresh fruits and vegetables), and plenty of mototaxis and taxis if you decide to go further than your own legs want to take you.
Definitely plan to take a half day at least to visit San Augustin Etla, home of a paper factory and an extraordinary art gallery--extraordinary for both its architecture and the quality of exhibits it hosts.
