Hi @tommarellofam and a warm welcome to the Community Forum 
We have met up with owners before a sit starts on several occasions, even when we have completed international sits. We have also arrived the day or a couple of days before a sit starts and have been invited by the owners to stay and we have had a chance to get to know each other beforehand which is nice.
For reference, as a member, you can also add your TrustedHousesitters profile on to your Forum profile by following the attached link, should you wish. This will then enable others to offer you helpful advice and feedback and will also give your listing extra exposure!
If you are unsure how to do this, or if you have any questions at all, do not hesitate to ask, we are all more than happy to help.
Also, remember you can use the spyglass symbol at the top of the page next to the TrustedHousesitters logo and search for any questions that you may have as they have most likely already been answered on here and of course if not then please just ask! 
I have attached a link and another thread you should also find helpful
