I've been twice in this hotel, but never slept there. My first time was in the old hotel, to visit my parents, in a thermal vacation. I only remember the huge pool.
My second time was recently, for a convention. I noticed that the hotel had a great "face-lift" and seems to be comfortable and fonctional. Luso is a mid age destination but the hotel tries to attract also young couples.
PS The huge pools stays there
