Thanks Ana and Guilherme!
It was a great stay!
The apartment is very easy to find and Guilherme (Anas son) gave me a warm welcome.
The apartment has everything you wish for in an Airbnb and was very clean.
The bed is very cozy, so you can just lay down and relax.
I wanna give a special thanks to Anas recommendation for breakfast at the Praça de Carlos Alberto (just a 2 minute walk). Great pastries (Nata, yammi..) and especially great bread (saying this as a German..)
Warm wishes from Berlin,
Sonja
