Maria's apartment was the perfect size for my husband and I during the week we spent in Santiago. Very clean and the building is safe with a 24 hour doorman. The apartment is just a short (5min) walk to the metro but since it's within walking distance of almost every attraction we wanted to visit, we hardly used it! We walked to Central Market, Vega Market, Saint Lucia Hill, Saint Cristobal Hill, Bellavista, Plaza de Armas, The Precolombina Museum - basically EVERYWHERE! Great location.
Maria's kitchen is well equipped and we cooked at the apartment for several meals as the supermarkets are nearby too. The tap in the kitchen has a water filter so water is good to drink. The bathroom has good water pressure and nice hot water.
Maria herself is one of the loveliest hosts I've met. She checked in on us once in a while via text to make sure we were alright. Knowing my husband is a chef, she even gave us a cooking class one day where she prepared amazing Chilean seafood. We all got along very well and the next day, we went out for a hike at Cerro Pochoco which honestly would not have been possible without the knowledge of a local.
All in all, if you want a comfortable place to stay with a great location and a host who cares about you, this is the place for you! We thoroughly enjoyed our stay. Would recommend! 5 stars!!
