Assuming you really want convenient offices, this is your seller! Ron was such an enjoyment to work with. Exceptionally useful and responsive. We as of late involved Posh Privy for our wedding in Temecula. We had around 100 visitors and Ron directed us in the correct bearing for what we wanted. Drop off and pick were consistent. Furthermore, did I make reference to how adorable these are!? They play music and are all around kept. Not one individual grumbled about utilizing them, as a matter of fact, we got a few remarks on what a smart thought it was to have “charming bathrooms” outside. We will involve Posh Privy for future occasions.
Thanks for your cooment. your comment Wil helps people a lot.
Posh Privy: Ron and Yolanda are a definitive dream group merchant! They are proficient, solid, and expert! Also, they endeavor on keeping the bathroom flawless for every one of our occasions! As a facilitator at a top scene in San Diego, we prescribe Posh Privy to our clients as a whole. I get such countless commendations post-occasion on how astounding the bathrooms are and the way in which they even smell wonderful as well! I would suggest leasing Posh Privy for an occasion or even area! :- )
