I read several reviews before booking, and was on the fence, worried about some of the comments. After staying there, it seems to me that Carolina is reading the reviews and taking action where she can.
I think most of how you feel about the space comes down to your expectations. I was in town on business, and stayed for a week at a 5-star hotel that was immaculate. It was in a stuffy part of town, and I wanted to hang out in a part of town where the action is.
My niece has been studying abroad in Buenos Aires, living with a host family. When she came over she was impressed... "If this is where I lived... I could see staying in Buenos Aires."
It is a funky, cool space. Carolina was so nice, and accommodating, and really went out of her way to help me arrive in this new part of town. I couldn't check-in before 18:00 (due to work) and she sent the keys over to my hotel. There was a miscommunication with the hotel, and they rejected the keys, since I had checked out earlier in the day. Carolina was very helpful, and came over and opened the place up, and helped show me around. At that point it was much later than she was expecting to be there. Thank you Carolina!
A couple comments about the things I was worried about... I read about the outside deck space being dirty. It was perfectly clean when I arrived. Birds do hang out there, but there is a hose and you can spray things down if you want. The shower is small, but wasn't horrible, and seemed typical for the area. Everything was clean, and nice... as advertised.
