We had a great time in Lisboa and the flat is awesome : super bright with a lot of windows, great view south orientation and no vis-à-vis, well located in a quiet street of a busy neighborhood we love, everything was clean, the bed is comfy...
The wi-fi is kinda slow and we were missing a few basic items that you wish you didn't have to buy for a 5 days stay like dish soap or oil or salt but we'll definitely stay there next time we're going to Lisboa!
