You should not book this hotel if you travel for leisure or a weekend. If you think it is a sheraton hotel - it is not the same as somewhere in the World. If you think it is a SPA hotel -as it say in the hotel name- than you need to realise that you need to pay extra for the acess to Pool and sauna area. I complained by the manager on duty, which was the F&B Manager. He promised to check this and call me in the room, but noone called and at check out I has to pay the SPA of course. This handling from a Manager on duty is unaceptable and unprofessional. Additional to that there was 4 hours no electricity, but reception not informed us before-as we come in the afternoon the was a letter in the room, but it was the time without Electricity. So 4 hours we could not work and had to re-schedule the day. All in all, the room is ok, but Service needs to be improved but Management is unaceptable unprofessional. And it is not the quality which you normally expect if you book a sheraton hotel! We will choose any other hozel in Porto for our monthly returns.
