The location was great, very central and easy to find. On a little side street, so nice and quiet at night despite being a stone throw's away from Bairro Alto and Rossio.
There is central heating, which I was worried about in Lisbon, so it's nice and warm even when the weather is not :)
The flat is smaller than suggested in the photos, but clean and cozy and with good working internet.
Nice little touches like water, tea and coffee provided .
Luis was nice and allowed me to pay the €20 fee for the late check at the end of our stay, as I didn't have cash on me.
