Ivan's place is in an excellent part of Lisbon. Very easy to get to from the airport. All the main sights are within walking distance or a very short walk to a tram or metro stop.
Check-in was easy. Ivan used a third party service which was efficient. The person who greeted us was very friendly and knowledgeable about the city.
The apartment was on the sixth floor, accessible by either one of the two elevators in the building. The air conditioning is fully installed with vents in the bedroom and living area which was very effective in the hot weather.
