There are so many wonderful things to say about Matias's place. It was spacious, clean, comfortable, and perhaps the most tastefully decorated and outfitted Airbnb we have ever stayed in. The check-in process was very smooth--Matias's associate welcomed us to the room and was very helpful and friendly. The location is a fun, more laid-back, neighborhood, that is very accessible to the center of the city. It was a great hub from which to explore. The only issue was that the air conditioning did not seem to be working correctly (and there are not windows in most of the rooms) so it got somewhat stuffy at night (it was a hot time in August). We tried to communicate with Matias about this but never got a clear answer on if they were broken or if we were using them incorrectly--we tried a number of different settings (besides the obvious 'cool' setting), but nothing we did could get the room cooler than 23 celsius even though they were all set for 18. That was certainly okay, but not the most comfortable. We were only there two nights. If we were there longer I'm sure an answer/solution would have been figured out.
Despite that, we would definitely stay there again (and you should too!).
