This place is awesome all across the board. The location is absolutely privileged, especially in a city like this where there's so much to see and experience, and distances can be a factor. There's a bunch of both useful and cool places at walking distance, and you're also quite close to important touristic spots within the city. I felt welcomed from the very start, the building's staff made sure my check in was seamless and they were very attentive my whole stay. When I arrived the penthouse was clean, everything in order and ready to use. It's quite the cozy place with excellent views from both inside and outside the apartment. Kukun was absolutely on top of things being very helpful and quick to every question I had regarding my stay. There might be some noise from the street at night/early morning, but you can use the fan to generate some white noise over it or put some earplugs on, and even then I didn't find it all that loud.
I recommend this place a lot, as it made my trip so, so much better. Would love to swing by again when I get the chance.
