Porto Bay Marques lived up to the Porto Bay groups' standards. Location ok (if you like walking). Fairly quiet, good well equipped rooms, nice bathroom. Restaurant Basilica attached, as always. Not quite as appealing as some other Il Basilicos mainly due to some inexperienced waitpeople, but the food was delicious. Very efficient and helpful reception staff, friendly too. The breakfasts at all of the Porto Bay properties we stayed at were fine, but they are all the same format and food. Would be nice if they changed the buffet menu sometimes. There is at least one other Porto Bay hotel nearby, Liberdade, which I would probably try next time when visiting Lisbon.
