Praia do Sal Lisbon Resort is located outside Lisbon in Alcochete. A rental car is the best way to get there which is fairly priced.Taxi fair there was expensive. Ask Taxi driver for a rate before setting off. I paid 70 euros! which is more than the retal I got at the airport later, price per day. There is a bus that passes by the hotel at least ten times a day that cost several or more euros to down town Lisbon. You will need a prepaid bus card that you can get at the airport (maybe you need to get it at the bus station, not sure.) which you use to tap on. I tried paying the driver with cash or a credit card. But he wouldn't accept them. Bus is ok but you will feel slightly trapped in one location. If you intend to spend a lot of time in Lisbon then learning how to pay and use the public tranportation may be better but for a short stay and particularly at this locaton, car retal may be your best option. There is a toll when you are about to cross the Vasco Da Gama bridge to Lisbon. But its only a few euros.
About the hotel itself. Its really quite good. Built of low unimposing third floor structures, with two or three floors going undergroung for an indoor heated pool and spa for one included amenity, its spacious. The breakfast baffet is high end and cost about thirteen euros. Or you can add this on to your resevation and save a bit. If you want to eat dinner at the hotel, book a head of time. It gets packed at night. All in all its a relaxing hotel with friendly staff.
