We enjoyed our stay in Marinho's flat ! The location was excellent, in a tiny alley which is close the castle which is on top of Lisbon. You will have a magnificent view of the whole city in the castle ! The neighborhood was full of people on day, but calm on night. The flat was a bit small but cosy and practical, the bed furniture was nice. We fixed the window by ourselves, it was really simple to figure out, our stuff was safe then :)
We recommend taking good shoes to get to the flat but also to walk in Lisbon (we made many steps a day ;)). You can also take the bus/tramway (which passes near the flat). There are also a lot of Uber drivers if you want to quickly reach some place :)
