Staying in Isabel's apartment was just great. It is well equipped and located very close to some of the most interesting parts of Lisbon. There are quite a few little supermarkets and nice cafés on the next street.
Isabel is a wonderful host, who does a lot to make you feel at home. Communication was fast and uncomplicated, the apartment was super clean and Isabel had prepared a few tasty local treats -- most of which didn't make it to the end of our five day stay ;)
