My partner and I stayed in the treehouse for 3 weeks and had a great vacation.
The owners have got all the big stuff right. The flat is very comfortable and, although small, has plenty of storage. The two outdoor areas are great in the summer. We had three maintenance/repair issues during our stay and the owners were very responsive to the urgent ones. The house was clean and tidy upon arrival. The neighborhood is residential and quiet.
We loved the short walk to Redondo Pier and all that it has to offer. We enjoyed each villages farmers market, especially Redondo Beach where you can buy handmade ravioli.
However, be warned that the view is not as purported. The overgrown pine tree and bamboo are partially blocking the view and the exterior of the front windows are filthy.
Also be warned that the bikes are in a sad state of repair and haven't been looked after. We used the bikes extensively and even though we paid for some repairs, did not feel entirely safe.
Whilst the kitchen has top end appliances, the pots and pans are Teflon coated, which has been proven to shed toxins into food. All the knives were serrated and not suitable for chopping vegetables (very dangerous).
At the time we stayed, there were no reviews of the property. We would have appreciated the opportunity to speak with the owners about our impressions.
