I have a 2 story house with a finished basement. I normally e-mail the owner Sev, to book White Lilac "on demand" every month or 2 when I am hosting a party or expecting house guests. There are always 2 cleaners (usually including Charlotte who is great) who do a thorough job cleaning all 3 floors within 5 hours. Generally, 1 of the cleaners is someone who has been at the house before. On my last cleaning there was an issue with a new team of cleaners who forgot to clean our basement and did not do a stellar job on the other 2 floors but I contacted the owner right away and they agreed to discount our next cleaning so I will give them another try.
