Cute apartment in an excellent location. It's clean and well kept, a bit small (as seen in the photos, no surprises here), but comfy. When you go out you'll find yourself right in the centre of one of the main streets of Lisbon, next to a metro station and pretty much anything else you can need. However when you close the windows you hardly hear anything from the street below, which is a nice surprise.
Communication was very easy. I found Miguel very friendly and happy to help.
All in all this is a good choice for anyone looking for a stay near Lisbon's centre, I would definitely recommend it.
