We had a good stay at Brian and Pablo's place, yet there are a few things that we found to be substandard to an Airbnb Plus experience. What was good: location is good - close to metro and within walking distance of nice places, checkin process was easy (code given to enter house), communication with hosts was timely, bed was comfortable, shower temperature and pressure was good, kitchen was equipped with standard dishware and cutlery and we could use the building common washing machines and driers on the 2nd floor. However, you never actually meet the hosts - make no mistake, this is a managed apartment, so don't expect warm hospitality per se. The entire place has a worn out feel and a damp smell - we opened all the windows the minute we walked in. Some of the items in the apartment are also stained and/ or dirty, such as the couch, curtains, shower curtain had mold, some of the dishes were dirty.
Overall we feel this is not good value for money, especially since it comes advertised as an Airbnb Plus experience.
All this considered, if you expect a okay enough place for a few good night's sleep in a good area in Santiago and don't really care about hospitality or cleanliness, then this is the perfect place.
