Loved my stay here and would highly recommend to anyone that spends some time in the city.
I won't go into the details that everyone has already highlighted such as the amazing location, but will point out a few things that are important to me for a long term stay, with remote working and as a solo female traveller.
The Wifi is great for remote work (video chats are no problem) You can set up a comfortable workstation at the table and even the construction next door was no problem at all.
The apartment has everything you need for a long-term stay ( I was here for 1,5 month) I often cooked - a mini oven, two cooking plates and basic cookware is available and I even found staple food items like oil, salt, etc were already there.
There are 24/7 security guards that are very friendly and helpful, I had no issues walking home alone, even at night.
Yula herself is a great host and is super responsive and answers any questions you have immediately.
Lastly make sure to take advantage of the pool and parrilla (needs to be booked in the house) as those places a pretty amazing.
In short, this is a great place for long or short term stay and I would go back in a hearbeat.
