The location was perfect- in the middle of the most exiting neighborhood in Lisbon, close to the river, public transportation and many great restaurants and bars. The lighted apartment is rather small, but has everything one needs (though the bed is old and not in good shape). Filipe was really helpful, waited for us, gave as many tips and let us have a late check-out.
In conclusion- if you're a couple coming to Lisbon, don't hesitate booking this apartment - you on't be able to get a better deal for this price.
