It s a really nice place, modern and spacious, right there in Alfama. I m happy we ve made a good choice.
We were there with 2 kids, age 4 and 6, they liked it too, the living room is not small, the loved the "balcony" where a lot of tourists and tuk tuks pass by. You get out of the house and you are right there where other tourists have to go to. We could walk around the narrow streets, explore from there and if you want to go further in the city, you can walk or there s the tram, there s the metro.
We didn t meet the owners, but we had nice email contact and it was no problem with the code to get inside.
If you come with kids and you are concerned about the stairs: they aren t too steep.
