I stayed for a few months in this unit. The host, Rosmary was the best part, as she was very helpful, informative and correct. Her professional and friendly interaction made my stays much easier.
The apartment is in good condition, nothing extraordinary, somewhat outdated. Photos are accurate. I did not have any service issues in/with the apartment. Most nights were peaceful, however as in most of the apartments in Chile (and Latin America), the sound proofing/insulation of walls, doors and windows is non existent. You are lucky if you don't hear your neighbor breathing... The building has a few disrespectful residents when it comes to uncontrolled dogs barking, loud overnight partying, etc. and enforcement lacks. If you are not sensitive to noise, you will be fine. I recommend Rosmary as a host.
