I was very impressed and happy with our stay at Vila Olarias and would absolutely recommend staying here.
The unit is spacious, clean and modern. Lourenco was very quick to communicate, gave clear instruction for check-in/out, making it all very efficient. We arrived earlier in the day and there was no issue accommodating an earlier check in. Lourenco also provided recommendations for dining, etc., which was helpful, since this was our first time to Lisbon.
We were very happy with the location too. Mouraria is in walking distance to all the main sights and neighbourhoods, but less busy and not super touristy. There are plenty of shops nearby for amenities and a bonus we enjoyed was a cafe just steps from the unit that made really good coffee! Directly in front of the apartment is a little square, which could be one detail some may want to take note, as Unit 10 is the one unit not within the gated entrance. We ultimately felt safe, but there are times we felt somewhat "out in the open".
Overall, we enjoyed our stay and would recommend without hesitation!
