I stayed there for one night in September 2011 (Room 103). Paid around 50 euro.
It turned out that I got one smoker's room.
After complaining about the strong smell to the lady at reception, they didn't offer me another room, but used spray to reduce the bad odor.
Room's furniture is from the 80s and looked terribly. Bed and pillow are uncomfortable.
Breakfast room is small, old and decorated in strange colors.
The breakfast itself is not worth mentioning. You get a better one probably anywhere else.
This place had seen better days and now needs serious renovation urgently.
Maybe some decades ago it was a 3 star hotel, but now I can only rate it with one star.
My recommendation: stay somewhere else in Sines.
