I just wish to correct some wrong info Mrs Chew has communicated.
There are currently 2 feeder bus servicing Botannia. One is provided by West Coast Plaza (which run between West Coast Plaza, Botannia and neighboring condo) and the other is by Botannia (which run from Botannia Ayer Rajah market and Clementi Mall)
The bus provided by West Coast Plaza runs 7 days/week and it start at 2.30pm till 9.15pm on weekdays and 11.30am to 9pm on weekend, with 45min interval.
For Botannia feeder, its 7 days a week including public holiday. During weekdays it starts from 6.30am to 8.30om with 30mins interval, during morning and evening peak hour, there are 2nd bus rotating at 15mins interval. There are 3 breaks per day, which is from 10am to 11am, 2pm to 3.30pm and 5pm to 6pm.
During weekend, the bus will run from 7pm to 6.30pm, with 30min interval.
I would recommend Botannia for people enjoy condo lifestyle, people who value space and green landscaping. It is actually very peaceful during the afternoon and evening, except for the occasional noise from pool side BBQ, kids play pool and occasional noise from resident's Lamborghini, Ducati and Harley Davidson.
Botannia has just achieved a record price of 1327psf last month. When hundred tree TOP next year and the launch of the mixed development project at HL garden shopping, price is expect to rise further.
I was told that the current wet market at Ayer Rajah wet market will soon have to make way for NTUC supermarket, and this should bring more convenience to residents living around that area.
As for schools and childcare, there are plenty. A search using onemap will show you all schools around the area.
Maintenance fee for a 4 bedder unit at Botannia is around $380, which is normal for most mass market condo.
