Help with questions about moving to Nairobi?

Hello,
We are relocating to Nairobi from Dubai. Looking to find a good apartment in Westlands preferably Brookside. Please advise or share your experiences on the below queries. Highly appreciate your valuable suggestions. Thank you!
1. Recommendations on good and secure areas / apartments to check out. Prefer child friendly with play area, swimming pool and gym. Closer to Parklands.
2. Based on my google searches, I have shortlisted few nursery schools for my child aged 3, which seem to be located close to Brookside area. If you have kids going to any of these schools or can recommend which is good would be very helpful.
A. Braeside school
B. Aga Khan nursery
C. My school Montessori
D. The Montessori learning Centre
E. St. Austin academy
F. Lavington kindergarten
3. And finally, I found a website - www.themothergoosekenya.com , which offers professional nanny and house help. Sounds reliable. If anybody has used their services or have better recommendations to find good house help please share.
Thank you once again for sharing your advice and experiences.
