Though the hotel was gorgeous, it somehow lacked the warmth of comfort we were expecting. Check-in was odd the way it was off to the side, and nobody really helped us with any of our questions. A concierge was not around, and any question we had was just quickly and somewhat apathetically answered. In fact, nobody even told us we could buy our train tickets to Lisbon online, which would have prevented a rush that resulted in my person boarding the train without me.
The breakfast was wonderful, and we decided to make a dinner reservation for the hotel restaurant. There were only 2 other tables with people, yet we were told that we had to sit across from each other, even though there was a bench that so easily could have been pulled out so that we could have sat next to each other. The hostess said that it would get in the way if somebody sat there, yet there was nobody there.
We were at the Epic Sana in Lisbon afterwards, and we returned to Porto for one extra day and stayed at the GA Palace. Those experiences were so much superior, and, when we returned to Porto for the last night, the concierge came running to us to give us all sorts of ideas for the last day. Honestly, we didn't even know that another part of Porto existed.
Perhaps if we were there as part of a convention or were able to use the magnificent infinity pool (it was raining the whole time), our stay might have been perfect. The room was perfect, but the overall feeling just lacked warmth.
