I would rate it rather Good, not very good. Our group was very small - 5 people plus driver/guide. Hotels were average, all very basic, 3 stars. Think, 4GTS should have done better for the price we paid. My husband and I visited Lisbon two years ago, so good for us, that time we covered all major sites.Time in Lisbon could be planned better. For example, we spent lots of time driving to other part of city for lunch (included) and when others got to Sintra, it was too late to visit a palace! Boat trip to private beach with lunch (included) - when at least 50+ people from two boats get on a tiny beach it become very crowded and lunch was not good. I would prefer to do just a boat trip which was amazing and cost less.
The walks took us through vineyards, small villages, celtic ruins and forests away from the usual tourist routes. It was an amazing trip into an area of terraced hills which has been man made over the centuries. The weather was very warm and it was a delight to return to the comfortable and elegant casa where the food was delicious and generous.
Our hiking trip in Madeira was spectacular. Hiking along the levadas and the hike that included Pico Ruivo were hikes that we'll never forget. The in-country support was very responsive, especially given that we were hiking during the Christmas holidays.
