Villa Maxima is very suitable for a larger group, we were 11 adults , perfect for us , and we had a wonderful stay there. Mostly we were VERY pleased about the house, don't forget that when you read on!
The villa is big and a bit difficult to find your way in, spacy areas and with sitting groups different places indoors as well as outdoors. Well kept garden mostly, VERY nice pool area, the water clean and fresh.
The rooms are nice, the double beds a bit narrow , and unfortunately mould in one of the 5/ 6 bathrooms.In the kitchen you find what you need , but it is quite small when 11 people want to take their share of the kitchen duties or want to prepare their breakfast to bring out in the garden. The sink got clogged many times, and we had to repair it.
Be prepared not to flush paper down the toilets, but this goes for most of Portugal.
There are shelves full of books ( a library actually) many about art, art lovers own this house , pictures on the walls and art in the garden.
We decided on not renting cars, we walked to the nearby areas ( Praia Grande, Praia Maças, Azenhas, Colares) , took the tram / bus to Sintra and the train from Sintra Lisbon. 15 minutes walk to nearest shop, very nice morning exercise. The twin brothers in the shop are very helpful.
What we really would have liked was a book/ folder with useful information ; ( transport/ time tables/ taxi number, shops/ mercado( where to find them/ opening hours), recommended restaurants ( like Central in Colares and Buzio in Maças), a bit of history / anecdotes, what to see f.ex. in Sintra, where to deliver tha garbage, house rules/what to do/ remember before leaving the house.)
We think you will enjoy renting this villa, as we did.
