Ana and Hugo were very accommodating during my stay. The location of the apartment is awesome: literally across the road from the Cais do Sodre station (and the river bank); near a ton of bus stops; around the corner from Copenhagen Coffee Shop; and right off the Rua das Floras, where there are a handful of great restaurants.
The only thing I would make sure that people are aware of is that IT GETS LOUD IN THE EVENINGS! I'm not sure what it's like during the week (I only stayed Friday and Saturday night), but it's at its loudest around 2-3am. I was fine with this (I brought earplugs and a sleeping mask), but that's definitely something to keep in mind before you get there, especially if you're a light sleeper!
