The view is even more amazing than in the pictures on the listing, and it was really fun to watch the clouds roll over the mountain, and climbers with flashlights start their wavering way up. The apartment is very beautiful, peaceful, clean, and secure (like, extremely secure). It's within an easy Uber ride to everything, and a 20 minute daytime walk to a shopping mall (my phone decided to break on my first day off) that felt safe to me. Many thanks to Saskia, who was a very clear communicator, and flexible with the check-in time when I got delayed.
Minor negatives (outweighed by far by the positives):
-It can get cold at night. Nighttime lows were typically around 10 to 12 C during my stay, and the only source of heat is a single portable oil heater (Salton SOH9), for some reason much weaker than other portable oil heaters I've encountered even on its highest setting. In bed with blankets with the heater on, the curtains closed, the bedroom door closed, it was plenty warm enough, but you'll want to bring a robe and slippers for when you're not in bed if it's going to be cold out.
-There happened to be light construction on one of the elevators during my stay, starting around maybe 8:30am even on weekends; but the noise level was more like "neighbor putting some paintings up" rather than "heavy New York City construction torture," so not so bad. The operating elevator worked perfectly throughout my stay.
And one last note, if you have a mobility disability or other mobility constraints, it may not be easy to get into and out of the bathtub, which is very high up off the floor. I don't have a mobility disability, but I still had to be very careful. I thought I should mention this since listings with an elevator are such a rare find.
