At the end of my husband and my first visit to Portugal, we stayed at the Hotel Star Lisbon. it was an easy walk from the Hotel to the airport. So we didn't need their complimentary shuttle service. It turns out this was the ONLY upside to staying there. Note also, that there are no other restaurants nearby except for the ones at the Hotel and inside the airport.
Luckily, we were given room two keys. My husband's key wasn't able to open our room door. Luckily mine worked. When my husband got a second key, it only worked the first time he used it but never again. I had to leave my key in the keyslot to keep the lights and A/C on when my husband left me in our room.
The complimentary buffet breakfast is included in the room charge. This seemed to be fine when I made the booking. However, just before our arrival to the Hotel, my back starting hurting me really badly. I missed all three breakfast we were there. My husband was told the he could not bring breakfast up to me either.
I was able to go down to their restaurant sometime after breakfast. By that time, only snacks (pizza and burgers) were available. These were obviously frozen items that were defrosted in the microwave. Very disappointing.
We will not stay here again on our next visit.
