My friend and I had a great experience with Nicolas himself-- he was friendly, very responsive, and genuinely helpful about the area, answering questions about the city. However, he messaged us before our arrival and asked us to move into a different unit than the one we originally reserved, and we agreed. I wish we hadn't-- that different unit was not up to snuff. It was very unclean-- the carpet was stained badly, there were hairs all over the insides of the sheets, there were recently-used towels hanging in the bathrooms, and the apartment smelled of a strong air-freshener odor to cover a funky mildew odor. After changing all the linens (as they were soiled), we spent one rather sleepless night there, and then found different accommodations. Perhaps the original apartment titled "Amazing apartment at Lasterria" would have been lovely, but the one he transferred us into was a bad one, indeed.
