My wife and I loved our stay. The apartment was exactly as described. It was cute, clean and had everything that you'd require for a short stay in Lisbon. It is indeed Comfy with a great feel & some great views.
Nuno was there and waiting before our check-in time and actually let us in a little early which was handy. He explained everything to us and gave us some great tips regarding Lisbon generally and the local area highlights for sightseeing and eating . In addition to Nuno's tips, the apartment features a map surrounded with a series of pictures of Lisbon sightseeing highlights with pinned references to the locations on the map.
I do have to mention that is that the apartment was a little chilly in the middle of January as there isn't any heating. Probably not an issue at all other than in the coldest of Lisbon weather but a small heater for the living area would be a good touch even if rarely needed. The warm doona/duvet and additional blankets provided ensured we slept very warmly.
The area is a great choice for staying within Lisbon. It's historic and full of charm & transport and sightseeing is all well within reach. We appreciated that the area is not dominated by tourists so you can happily walk around and feel absorbed by a Lisbon life experience rather than only experiencing a superficial outsider's viewpoint. We pretty much fell in love with our surroundings and the great and affordable eating.
If we come back to Lisbon we wouldn't hesitate to stay again.
