The Radisson SAS is a four star hotel, situated five minutes from the Lisbon airport and within a five minute walk to the Metro station (subway).
The hotel is definitely four star. The room was large, clean, and well appointed. The bathroom was spotless and shiny with all the amenities, i.e. hair dryer, 120/240v plug for a razor or hair dryer/curler, and a good supply of shampoo, etc.
The room had a queen size bed (almost unheard of in Portugal), a couch, table and two side chairs, as well as a bar fridge and satellite TV.
The service in the hotel was exceptional - everyone was friendly and very very helpful. They even offered to follow me to the airport to drop off my rental car and then drive me back to the hotel.
The stated room price was 140 to 150 Euros per night ($150 to $160 US, $230 to $250 CAD), but we got the room for 80 Euros.
The Metro was only a five minute walk from the hotel. The Metro was a 15 minute ride to downtown Lisbon.
There is no swimming pool, sauna, or whirlpool at this hotel.
