Luís’ apartment is nice and just blocks from the train station, quite convenient for my trip from Lisbon for just a few days in Porto.
The communication was great and while minimally decorated and appointed, all of the apartment is in good taste and nicely designed / laid out. There’s some noise from the streets but the wood shudders reduce to manageable level in the bedroom. And yes, there are occasional sketchy characters below, but the apt door is right off the main street there with people around.
If you’re looking to be central, this place is great. If you want to be more local and avoid throngs of tourists, it may help to get a place farther from the center.
