    Had to stop by to get something mailed out. I was a little short with the lady as was in a hurry, she did a great job though. They take care of things well here

    Applied for my passport today at this location. Made an appointment and it only took about ten minutes! Super duper easy, friendly, no fuss at all. Even had my photo taken for the passport there. Would definitely recommend to use this location for passport needs. New location in Goodwives has a ton of easy parking and it wasn't busy when I went at 2pm

    If you want your mail to reach it's destination, DO NOT LEAVE IT HERE! My bill payments have been lost not once but several times with one of them (electricity payment) being returned with undeliverable stamp on it! I posted a payment to City of Stamford for parking violation THAT NEVER REACHED THEM! I now use the mail department at work here in Stamford. APPALLING SERVICE! (less than one star if I could)
