Este es un apartamento excelente! My friend and I stayed here for about two months and a half and loved it! Jorge did a great job of checking in on us via whatsapp to make sure that things were going well and was always speedy in helping us out whenever we needed.
As for the apartment itself, I found it to be very clean and comfortable. It was a bit cold to hang out on the balcony, but we got some good use out of that on sunny days. If you´re staying there in the winter like we did, you´ll be happy to know that there were heaters so we could stay nice and warm (some apartments in Santiago do no offer this). Also, the beds were comfortable and the stove in the kitchen worked well. There is also someone at the lobby 24/7 to let people in and out of the building, which made it feel safer.
On top of being a cozy apartment, it was a fantastic location! It´s an easy walk to both the Slavador and Manuel Montt metro. There are plenty of restaurants, cafés, bars and nightlife just a few streets over. It´s located about in the middle of the city, so most of the interesting sites and things to do tended to be no more than 20-30 minutes away. The street that the apartment is on is very residential so it´s calm and quiet at night (except for the occasional fire truck). Overall, we were very happy with our stay and recommend choosing this airbnb!
