We had a great time in Porto and Mariana’s apartment is in a great location that’s convenient for walking around the city and crossing over the bridge to visit the wine caves. The place was exactly as described and even brighter than pictured due to the nice high ceilings. It is an old building though, so while outside noise was not bad, you do get some upstairs noise and the bed is creaky so agree with other reviews that suggest earplugs if you’re a light sleeper, although if you’re eating and drinking around the city you might not have a problem :) There are also some great recommendations in Mariana’s guides so suggest taking a look!
