My stay with Matias was absolutely delightful. :) From the very beginning, he made me feel welcomed and comfortable - having a pot of coffee waiting for me when I arrived. (definitely needed after traveling all night!) The room is exactly as shown in the pictures and feels even more spacious in person. It is also facing the inside of the building so it is quite and tranquil. The apartment itself is also very comfortable - with lots of spots to work from your laptop like I did.
The location is absolutely amazing! You are right next to the Botanical Garden which is my favorite spot in the city to go read and relax but also within walking distance to many different neighborhoods and of course great restaurants and shops. If you are looking for a really authentic way to experience this city, then staying at Matias' place will definitely be for you!
