As the shoujo-ai genre goes, I think of this as one of the best I have seen. Not too serious, not sad or full of drama. It is light hearted, funny but has some real warmth.
This a slice-of-life comedy with little plot other than the development of a relationship between Akari, a school-girl with a love of dolls and Sophie, a vampire who despite being several hundred years old still retains the appearance a girl of Akari's age.
The music in this anime is very good with some very catchy OP and ED songs.
Artwork is effective. There is Interesting use of color with lots of reds in Sofie's house. Character designs are memorable.
Considering that there was at least one volume of the manga released after this anime aired, I am hopeful that their might be another season or perhaps an OVA for this anime.
