We really enjoyed staying at Carlos's lovely apartment, from the moment of booking Carlos was very communicative and went above and beyond to make our stay a great one and welcome us to Lisbon. He even tried to collect us from the train station but our train was running very late so we ended up finding our way to the apartment ourselves.
Getting around is easy though and after a short metro ride and walk we got there fine. The apartment is in a great location, walkable to pretty much everything and has a fantastic view across the city. The photos (and all wide angle photos do this!) made the place look gigantic online. It is very spacious in the main living space, just not as cavernous as the pics make out.
The only thing that could be perhaps looked at was the drains situation in the bathroom, we noticed that in the hotter weather especially they did start to smell quite a bit. Maybe this can't be helped in the old buildings but otherwise it was perfect.
