We stayed in Michael's flats for about a month in October 2022. Michael is a very helpful host and purchased items that we requested for example an iron and ironing board.
The quality/price ratio is very good as we paid 50% more for AirBnBs in Vitacura (i.e. about 3+ pesos million a month and Michaels place was only 2+ million a month)
The flat is clean, has a great view of the mountains and is relatively quiet (at some point in the future there may be building work outside, but not at the moment). The main bedroom is of a good size and the second bedroom would be OK for two children as there is a bunk bed. There is a secure car park space and you can use the visitors parking for up to 12 hours if you have two cars. Alto Las Condes shopping mall is about 5-10 minutes walk away and there is a nearby park for children. Autopista Kennedy is close too.
If you like cooking and plan a long stay then this flat may not be the right one for you as the kitchen is quite small with limited cupboard space. There is also no washing machine (but the building has a washer and separate dryer in the basement for which you pay 3000 pesos or about 3 dollars per wash/dry) or dishwasher.
Thanks to Michael for renting out his flat!
