I booked Villa Grabella to hold a week-long intensive writing retreat for my research team from the University of Amsterdam. There were 10 of us. We had a marvelous week, the house is very comfortable, airy, and nicely designed. We all found spaces to work and hold meetings, and as a result we accomplished a huge amount of work. Antonis's mother Maria met us on the first night, even though we arrived at midnight -- she had cooked dinner for us. A couple of minor practical issues came up during the week, and Maria was there as soon as I emailed Antonis, even in the late evening.
This is a wonderful place, run by charming people. I particularly recommend it for groups which, like ours, need a place to retire to get work done. Thank you, Antonis and Maria.
