The appartement is very well located next to the ocean, not far from Bairro Alto where all the bars are. There are cabs 100 meters away from the appartement, from which you can access all part of Lisbon very quickly at a cheap price.
Appartement is functional, owner is very nice and happy to answer any question you might have before and during the stay.
If I had only one critic, there was a very bad smell in all the appartement, especially in the toilets and the kitchen. Appart from that we had a really nice stay and would recommend it.
