We had an enjoyable stay. The flat is in a fantastic location, next to Cero Santa Lucia and the streets cafes restaurants next to the flat were wonderful esp. Boccanariz wine bar which we much preferred to Mesizo out in Vitacura neighborhood.
The flat has got character and I like the decoration w old antiques / items. Its also wonderfully sunny w the sky light spilling tons of sunshine into the very high ceilinged flat. I'm beginning to appreciate that a lot of Chile is sort if shabby chic and that's part of the charm (?) In any case we had a good time, my family enjoyed having breakfast on the rooftop terrace, lying on the couch next to the window reading, etc.
The hosts were very nice and spent time speaking to my fiancé and was very helpful looking into car rental for him etc.
The host maybe new to renting out so there were some teething issues. It was not a huge problem for us, but there are 56 steps via a long narrow wooden stair case to reach the flat. The water pressure could be better but its probably the same everywhere, the hot water was a bit stop and go. We found the trick that if you let the tap on small trickle of hot water on over the sink, the shower stayed hot rather than having to stop and start from very hot water multiple times. The towels were brand new etc, and cleanliness we weren't sure what's the norm in Chile but perhaps could be improved.
Overall we'd recommend this especially for the fabulous location and I'm sure the experience will be even better for the next guests.
