We had a lovely time at Marie Antonietta's Trulli, we never actually met Marie Antonietta although her friends were very lovely and helpful.
We came with our 15 month old baby and a cot and bedding were provided, the house was great for him to walk around.
We loved the location as it was in a lovely little village but only about 20 minute drive to Alberobello, Locorotondo and the coast.
I would say the inside of the Trulli wasn't exactly like the pictures it was slightly more old fashioned but it was nice.
