Very friendly welcome from Ze, who was helpful in telling us about the area and the city. The apartment was generally clean, with very clean bedding and towels etc, however somewhat smaller than the photos suggest (but perfect for 2, possibly 3).
Our main issue was major building work, just behind the flat, which was very loud and intrusive (starting at 8am). We did speak to Ze about this, who offered to compensate us with a breakfast in a cafe, and we understand that the building work has only recently started (which explains why they didn't warn us before our stay).
Nevertheless, the flat was very nicely designed and very comfortable for us, in an interesting area of Lisbon.
