We recently stayed at Bay Lake Towers for 4 nights.  The number one thing about this resort Is it's proximity to the Magic Kingdom.  It was a quick 10 minute walk from our room to the park entrance.  We found our 1 bedroom lake view villa to be spacious, clean, and comfortable.  Having 2 bathrooms and a washer/dryer in the room was also wonderful.  While this resort doesn't offer the over the top theming of some other Disney resorts, the subtle hints of Disney was refreshing.  We found the staff to be helpful and friendly.  One thing that could be a negative to some is the lack of access to dining and drink refills in the building, but it is just a short walk to the main Contemporary building where these things are located.  There are also great dining options in the main building, with a good variety of options for everyone from small children to foodie adults.  We also found the lobby could be very crowded, especially during check in and check out times.  We would definitely stay here again and recommend it, especially for those looking to be close the Magic Kingdom.
