We stayed at the Quinta das Custas in August with two families and had a great time! Lots of space, nice views, 3 swimming pools, good beds and a nice garden for kids to play around the house. Very quiet location only to be disturbed in a pleasant way by the shepherd and his goats and sheep walking by in the morning. Well serviced and we were helped well and quickly in case of questions. Lagos is a 20 minute drive, nice beaches near Burgau only 10 minutes away, fun restaurants in Salema 15 minutes. Only one small nuisance, keep everything very clean all the time since the ants are very quick to get into the house.
We spent a full week at QdC, the house is very nice, enough space for 2 families comfortably. Surroundings are ideal if you want to avoid summer multitudes. Views are beautiful. Service was kind and efficient. Highly recommendable.
