Me and my girlfriend went last week to Portugal and rented this amazing apartment in Bairro Alto, the location is really good (you are in the center of the city and close to everything)
The apartment is amazing and internet is great (a pocket WIFI that you could have with you around the city, all day long)
Paulo was a friendly host that gave us a few tips about the new trendy places in Lisbon.
Definitely, a place to go back!
