We were looking for places in Florida to travel to from MI. We decided St Pete Beach after I realized it was rated as the #2 beach in FL by trip advisor. It's also only 25 minutes from the TPA airport. We are from Atlanta so we know Florida very well and thoroughly enjoyed St Pete Beach!
The unit and owners were fantastic. The communication was great, Paul and Robin were quick to reply to any questions and issues we had. The unit had everything that we were looking for. The pool/hot tub were nice in the evening, the beach is right in front of you and we enjoyed a surf and turf dinner using the grills provided by the pool area.
If you don't feel like cooking (which we didn't most nights) there are many restaurants/bars/grocery stores within walking distance. You really don't need a car here--we rented a car for the week but basically only used it to travel from and to the airport.
The comments about the "noise" are a little misleading. You are by a somewhat busy road, but you are also staying on the most popular strip on this beach. If you want a really quiet trip you should expect to stay somewhere that isn't beachfront or within walking distance to so many great attractions. We kept the doors and windows open and were not bothered at all.
The trip was everything we expected and more! Hopefully we can work out another return visit soon.
