My husband and I spent one week in Matias's place in November 2018. First and foremost, the location was excellent. We were within walking distance of tons of great restaurants and parks, and the area seemed very safe. Second, the building amenities were a nice bonus. We used the pool area a couple times (very clean and stylish), the gym (not tons of equipment but it had the basics and was clean), and the laundry (very easy and cheap). Third, communication with Matias was easy and quick.
The unit itself was pretty much what we expected based on the pictures. It was enough space for the two of us, and the kitchen was sufficient for making breakfast but was not especially well stocked if you wanted to do a lot of cooking. The unit was a little bit run down (e.g., could use a new coat of paint), but the bed was comfy and the AC worked well. Overall, we were happy with the experience.
