Great location, the facilities around the area are first class. It's a bit awkward to get to from the airport, but we used Mario so that got us around that problem.
Once there the transport links are excellent, jump on the tram, the bus or the funicular to get you around. Day tickets for the transport system are a must, the Via Viagem card is perfect, include the ferry for completeness. Tickets only available from Metro Stations.
All the restaurants we visited drop the starter on you without asking, none took offence when you say no and take it away.
For a special, unique bar, pop across the road to Pavilhao Chines, ring the bell and see if they let you in :)
