Marco's place is great. We communicated with Helena throughout the trip who was tremendous. Helena was very quick to respond and went above and beyond to give us some great notes about Lisbon when we met with her at the beginning. It was a great location for us - close enough to the airport and busier areas then quiet enough for us at night. We did a lot of walking and only took an uber (always a very short wait) a few times for stuff farther away or when we were running short on time. I wouldn't hesitate to stay there again next time I come back to Lisbon. We had zero issues with our stay - loved the patio and view of the sea and have no doubt that Helena would have helped us with any issue if we had one. Very grateful to have had this place for a week.
