I absolutely loved this apartment. I stayed here for about 6 weeks while working remotely from Buenos Aires and it was perfect. It has a big living area, strong WiFi, fully equipped kitchen, laundry in-unit, lots of storage space in the bedroom. I think it's a great option for longer-term stays, I felt really at home here and was sad to leave.
The location is great, such cute shops and restaurants and bars, near the Subte and lots of buses. There's also a coworking space around the corner. The building is in a classic style and has a nice roof terrace to hang out on. I felt safe coming home late as a solo female traveler.
In addition, Kris was very responsive and accommodating - he allowed me to check in very early in the morning. When I arrived, the fridge was broken, but he had it replaced with a brand new one within a few hours.
Will stay here again if/when I come back to Buenos Aires!
