The location was excellent; with Alfama on one side with the magnificient restaurant Chapito overlooking the city, and the busy downtown area of Baixa on the other hand. You've got the whole city at your disposal.
We were a group of four, and we had all the space we could ask for.
The pictures don't do the apartment any justice; from the west facing balcony, you can see the Tejo River, and from the kitchen you can enjoy your morning coffee in the light from the rising sun.
The neighborhood is great. The shopkeepers were nice and helpful.
The street is busy, but when the windows are closed, you can't hear anything from the outside.
We called the apartment owners at the airport, they got to the apartment five minutes after we did, so everything was great and hassle-free. The same goes with the departure.
