Everything was perfect. We stayed two days and when we arrived at the place Grinuy explained us everything about Lisbon: she gave us maps, travel cards, guides about restaurants, bars, monuments etc... She prepared also food for the first night :D.
The house is beautiful and clean, exactly as you can see in the pictures. We only walked about 10-15 min to the center.
I highly recommend Grinuy's place, if we return to Lisbon we'll definitely repeat!
