We've often gone to places with AirBNB that didn't really live up to the photographs. This apartment wasn't one of them. If anything it was better as we were expecting it to be pretty small from the pictures and it was definitely spacious enough for us - much more so than anticipated. The balcony is really excellent with superb views of San Cristobal and the Andes to the right/east. We had a fantastic New Years eve there watching the fireworks around the city. The apartment was very clean and the beds, bed linen, towels etc all very good quality. The kitchen is well stocked and we did eat in often enough that we used everything. Having a dishwasher was also really convenient. The pool is nice and very clean and the gym, whilst small had decent equipment and was well kept. We were in the apartment for 2 months and would have stayed longer if it had been available. The area is very good and there's a decent enough supermarket just a short stroll away. I'd not hesitate to stay in Felix's apartment if we come back to Santiago. He was a great host even though he wasn't close by. He gave us some excellent recommendations for places to visit and also restaurants to try. He was very responsive to any messages and allowed us a later check out as we couldn't get into our next location early. Very friendly and helpful.
I'd highly recommend the apartment and Felix as a host.
