This is a very good value apartment - central location in Alfama, very stylish and well equipped, with friendly welcome and great communication.
There were a few downsides. The building next door is a construction site and on the Friday the noise started at 8am and continued all day. This stopped at the weekend, but the building 2 doors down is also a construction site and this continued all weekend. It wasn't as loud, but still could be heard. The whole of Alfama (and Lisbon) seems to be on a construction boom, so could be quite hard to avoid if staying centrally!
The apartment is quite dark and during the winter a bit damp and cold (though plenty of heaters are provided). While it has outside space, there isn't a view and flanked by construction, it wasn't a great spot.
