We had a great 2 week stay in Monica's apartment! The kitchen is well equipped - we did lots of cooking and some baking whilst we were there. The flat is spacious - there's a sitting area and also a breakfast bar with stools to each your meals at. The bathroom is nice with a deep bath tub and lots of super hot water to soak in. The bed is comfortable and plenty of space to put away things in the drawers and wardrobe.
The gym in the block is very basic but there's a couple of bikes, steppers, cross trainers and a multi resistance machine. The small pool looked nice but too cold to use it in June!
The location is also really great - it's right on top of Santa Lucia metro station, and also only 20-25mins walk to Plaza de Armas and Lastarria for bars and restaurants. There's a pharmacy, bakery and other little shops right by the apartment block including a great sandwich/burger place on the corner. It's a 10min walk to a bit UniMarc or 5mins to a smaller LiderExpress supermarket. They've also just installed BikeSantiago bikes right by the apartment (although sadly you have to be a Santiago resident to sign up!). There are also lots of bus routes right by the flat, I took the bus to Providencia every day to go swimming in a 25m pool there, and it was very easy.
Monica was very attentive - responding very rapidly to any questions we had.
All in all- a great place to stay- felt like a home from home! We actually extended our stay as we liked it so much!
