Catarina and Alexandra are the nicest hosts. They both gave us useful (and dedicated!) advices for our stay and were always fast in answering the messages.
Our room was nice, maybe a bit small, but it works just fine if you need it for a couple of days.
The shared spaces are large and with a lot of sunlight.
We weren’t so lucky with some of the other guests, who were quite noisy and messy, but that’s a whole other thing and I guess it just happens.
The apartment is very well located and I would suggest moving by feet to the city center, where you can take buses or the subway to go further on towards the beachside (Foz or Matosinhos).
