Pros:
Best hosts ever. Javi and Tammy did everything under their control to ensure my stay was optimal. They got me a desk and chair for me to work from their place. They even bought a new microwave machine when I mentioned I would need one for my long stay. They were always humble, friendly, quick and very helpful when communicating with me.
A really secure complex, the whole block is gated with two entrances monitored by cameras and security. Only residents with a fob can get in.
Comfortable beds and couch, perfect for a group of 4 or 5.
Pet friendly. My mom came to visit me a few times with her dog and Javi and Tammy did not have any problems with it.
AC in the living room and fans in the bedrooms.
Essentials like towels, basic pantry stuff, shampoo and conditioner, soap, and bed sheets.
A little balcony with a pretty view of the old buildings around Abasto area that allows you enjoy the pretty sunset.
Wi-Fi was consistent and fast and didn't show any issues during my stay.
In-unit washer. Just make sure you don't change any settings until it reads "fin" when using it.
Cons:
The apartment can be pretty loud due to the thin walls and ceiling and because there's a playground next to the building that you can see from the balcony. Windows are not soundproof.
The kitchen stuff is a bit old if you are planning to cook often.
The place may need some deep cleaning but I'm sure the hosts do their best and if you ask, they'll take care of it. You may find little cockroaches sneaking into the kitchen at night. This is common in older buildings in Buenos Aires.
Bathrooms don't have any ventilation so you may need to leave doors open, especially when showering.
Hot water is limited and you may need to take breaks and wait if there are multiple guests staying.
Overall, I felt very comfortable counting on Javi and Tammy during my stay.
