Yes, although an address is required in order that you appear in location based search results. We recommend putting the postcode of the local shopping centre or similar, so that you appear in the search results.
For online booking there is the option of being exclusively mobile and thus clients will be required to enter an address.
Alternatively you can select mobile - on request via your specialist profile and this will mean that clients have the option of selecting your business address or inputting an address where they wish for you to attend.
Once the booking has been made then you will receive contact details of the client as well as the location so if it is not convenient you can give the client a call to discuss.
