We stayed there in August/17, my family (4 people) and we're very well impressed with this hotel. Good staff, but some of the attendants don't speak English - better if you have some Spanish to communicate. Generally, the key points: good apartments, with 2 rooms and a sofa-bed (good for 2 couples + 1 adult); a small kitchen for fast meals; breakfast is included, simple (don't expect a full breakfast in American way but something more "european" or "latin" way); quiet rooms, good heating system. Only question is hot water, which is available for 30 min. But there are clear advices about.
Localization: 10min walking to the Manuel Montt subway station. There is a Rent a car in this station, good option for short trips such as Valparaiso and Vina deal Mar (we did this). The next station is Pedro de Valdivia, with dozens of currency exchange shops. Neighborhood is very calm and sounds to be safe. Generally, a place were I'll certainly return!
