Cinta, I've never ordered from Logees but I used to hear good things from folks on DG about their plants .. only bad thing I think I heard was the shipping charges were quite high.
Oh yes ... Gardenias and other fragrant plants can be quite overpowering indoors! I keep quite a few plants indoors but nothing that blooms with fragrant flowers. One time a few years ago when we were having an extremely cold spell during the winter, I moved a few hoya plants inside. They happened to be varieties that are winter bloomers and I ended up having to move them back out to the porch because I was having breathing problems ... beautiful fragrance but oh, so overpowering!
