Silvia is a brilliant host, I've never felt so welcomed through all of my experience with Airbnb! Thanks for all the tips you gave me, all of them turned out to be super useful!
The flat is fairly simple, however it has everything you need to feel at home, besides Porto is a great city so you won't spend a lot of time inside - go and explore! The flat location allows you not to think about public transport much, and in case you need to go somewhere far, it's located right next to the main metro station of the city. The shower and timing - well, come on, it's not a big deal, less time (and water) wasted - more time to see the city! I am absolutely in love with Porto and hoping to get back as soon as I can!
