Google Maps/Places API with ASP.NET

Question

Hello,

I am a bit of a newbie at this since I just started learning it. I am trying to do a web service that will get hotel reviews and rating based on a user's geolocation using the Google Maps/Places API while using ASP.NET. So I want it where all hotels will show up in my area and I can click on each marker and it will display information along with the reviews/ratings. I know that you have to use Google Maps to get the map display and Google Places to get the reviews/ratings.

I have read the Google Developer site and have obtain an API key, but I am still completely lost, so if anyone could help me out with this, I would greatly appreciate it!

Thank you!
