I highly recommend this apartment. It is well located in the Bairro Alto neighborhood, surrounded by restaurants and bars. Very clean and comfortable. As per some past reviews, there is some street noise in the evening but only on the weekend because it is a popular area for nightlife, however the windows are double glazed and the noise really didn't bother us.
Patricia is a wonderful host and really made us feel comfortable to ask her anything at any time. She was very responsive, and greeted us at check in with a lovely bottle of wine and some Portuguese tarts. Her restaurant recommendations were spot on too!!
The apartment also comes with a portable wifi device which is really handy if you don't have roaming.
Easy access to taxis which can be hailed on the main street a block or two from the apartment.
