In Quinta do Lago area. Large area spanning through 6 roundabouts on perfect roads with the usual exotic flora and fauna. Quite pretty in fact and most obviously designed as a home area for wealthy villa owners/timesharers/5* hotel- and golfers after the PGA quality courses. it's probable about 2 miles long and wide. A car is essential if you desire to travel further afield than the beach or off to night clubs(taxi) etc...
The townhouse set up was nice, designed off the slip roads to the bobby jones bar and restaurant, reception, supermarket and pool/gym area. Garden space to the villas was poor, but this was a dedicated site to golfers really so you are virtually on holiday on the fairways of north and south courses. You can walk to ria formosa and san lorenzo, more so if you are a golfer, it's only ten to 15 minutes trot.
It was nice and even you could say, romantic if you plan your evening meals around the gorgeous food you can have locally. And the fish restaurant on the beach actually works out cheap if you are in a large group choosing a sensible variety between you all, picking the fish eyes tail and all from the ice counter yourself and paying by the weight(it's quite proper)and served overlooking the ria formosa lagoon from the wooden stilted restaurant.
Off resort- there is vale do lobo and the beach font restaurant piazza is lovely- this is a heavy time and owner occupier area , holiday home to the likes of Gloria Hunniford and family, Cliff Richard, Trevor Brooking, Jona Barrington, Ken Hom had a restaurant here. It's classy, easy going, nicely built resort... away from timeshare country you can drive to the hell holes of the algarve and this is my opinion but they don't have a clue to make a harbour/marina look great and ideal like the Greeks or other med areas. I can honestly say don't waste your time, don't go there(as listed now)Villamoura, Praai do rocha, Portimao, Quarteria AWFUL!!
There are other areas i'm told are nice in places or lovely like carverio, lagoa, albuferia(jurys out- built main resort)- these must be worth a look? other than that don't bother...
Lastly, Vala do Lobo, Quinta do Lago excellent to get through your week alone. Brilliant restaurants and resort facilities, beaches are quite fine. My favourite restaurants were here and the melting pot pub had wonderful singers/guitar on Fri-Saturday nights doing Eagles, Meatloaf, Beatles, Bryan Ferry etc...
