Everything was fine.
The only thing, is that it would be great if they can get a key lock box to leave it outside.
We arrived at 21:20 and we had to pay the 20€. It was in the ad, but we expected to have some breakfast ready in exchange (milk, biscuits, fruit... nothing too fancy)
Other than that, Jon was really nice all the time and the house is as you see in the pictures.
It is in the middle of a heel, but very close to barrio alto and there are a few coffees around.
I guess it is good value for money as everything else around is a bit more expensive.
We would recommend it, specially if you arrive to Lisbon in the morning.
