I stayed here for a full month in May 2021 to work remotely (taking zoom calls all day inside the unit) and totally loved it. It faces south so gets a bunch of natural light all day. It was clean (the cleaners come every day to clean all the units in the building, it's up to you if you want to utilize them), comfortable, modern, had nice modern kitchen amenities, and had fast wifi with no issues during the month I was there. The location could NOT be better, directly on Calle Amsterdam at a very quiet intersection with hardly any vehicle traffic. And having a cafe/restaurant downstairs was a great bonus. All of the staff from the restaurant and the cleaners were exceptionally friendly and helpful. Although it's a bit pricey, I would 100% stay here again, especially if working remotely.
A couple of things that you should know before booking are:
(1) the restaurant gets set up every morning starting around 7:15am and opens at 8am. This unit is directly above the restaurant. There's a decent amount of "furniture scraping the floor" noise as the employees move tables and chairs across the floor and then open doors and windows with cranks, etc. I sleep with earplugs, so this didn't bother me at all, but it's very likely to wake you up at that time if you aren't wearing earplugs. But after 8am the set-up noise stops.
(2) at the time I stayed there, there wasn't a desk or chair that was suited for working remotely all day. I bought a cheap desk ($30) and chair ($30) second-hand off Facebook Marketplace (delivery included!), and then I had a great work-from-home setup for the month. But the place does not have such furniture included by default. (I took the WFH setup with me when I moved to a different place after the month was up.)
Overall, though, this place was near-perfect, and I would definitely recommend it to anyone.
