Maritza's apartment is 100% the perfect base to explore Santiago. It's located only a 5 minute walk from Plaza de Armas and is surrounded by shops, supermarkets, and cafes, so you can always grab provisions. Most importantly, taxis have no issues finding the building, which is great!
The apartment itself is compact but extremely comfortable for two people. We stayed a week and felt right at home. It is fully stocked with all the amenities listed, including a washing machine, smart TV w/ Netflix, WiFi, pots and pans etc. The bed is absolutely HUGE and very very comfortable, and the walk in wardrobe is a great place to store bags out of the way. We also felt very safe here with the 24 hour concierge being available. Maritza was a truly lovely host; helpful and always responsive.
The ONLY thing I would point out is that there can be a lot of noise from upstairs neighbours (banging at 3am most nights) and the street below, so at night you might want to bring earplugs to help with sleep!
