Diogo and Rita was very kind and helpful, I think they are perfect hosts. They made us a very useful map and gave lots of informations about transport, which train/bus we had to use, the current metro strike etc.
The home is a best place to stay in Lisboa, very clean and lovely place and it's very close to the metro station aor you can get the downtown by foot in 15-20 minutes. We loved it, so we can warmly recommend it if you travel to Lisboa!
