In general, this apartment was fine. It was clean, kitchen was well equipped, check-in went well, the hosts were friendly and helpful, the neighborhood was safe and VERY conveniently located within two metro lines. A good price-to-quality ratio in all of these. The room window wasn't straight out of the apartment, though, but to a kitchen alcove of sorts, just next to the big courtyard windows.
Otherwise a strong 4-star rating, except for the noisiness, which unfortunately made it a 3 for me. I was sleeping with earplugs on but still I woke up often during the night or too early in the morning to doors slamming in the corridor – apartment door, bathroom door or room doors – and people searching stuff from the drawers in the kitchen. On my last evening, when I needed to get to bed early for a morning flight, some neighbouring apartment in the building was playing loud music. There are also airplanes departing over the roof, but surprisingly they didn't really bother me.
