Antonio met us at the airport for pick up to the apartment. He was friendly and welcoming and gave us lots of tips for our stay - places to visit, restaurants etc. Antonio was very accommodating and let us leave our luggage until late afternoon at the apartment since the next guests were arriving later.
Location was very close to Rossio square, a few minutes walk so very convenient. The apartment was light and airy, very clean and stylish.
Only slight negative was the people below being a bit noisy, loud music playing (although this didn't go on late) and being loud when coming back in late. Obviously this is something Antonio would have no control over and it caused only minor disruption to the stay.
