We had a really nice time! We stayed for 4 nights at Carlos & Claudias house to visit Lisbon. The train is very close, so we got to Lisbon very easily.
Carlos & Claudia are very nice, friendly hosts, and they recommend a Café just around the corner for breakfast (and we also got the coffee for free thanks to vouchers which we got from our hosts).
So again: thank you for having us at your house :)
