The apartment was really neat and Litsa friendly and helpful. As expected it was located about 1km from the airport which we could walk, since we had big bagpacks instead of suitcases, even though the sidewalks vanished several times and we had to switch sides or walk on the street. Since the airplanes started right above the building it was also noisy as expected, but it was okay at night with earplugs and a less crowded flight schedule.
Quite a problem became the technical difficulties we had during our stay: the AC was only partly working in the living room and was broken in the bedroom. Therefore it was really hot for us. When we told Litsa about it, she ordered a mechanic, who just couldn't fix the problem right there. We were offered a fan, which worked for us. We also had some issues with the TV and the WiFi... Once these issues are fixed, the apartment is good to go for a night or two.
