girl looking for a cheap room in Madrid centre or in Alcala de Henares with central heating

My name is Sandra and I would like to share a flat with Spanish people if possible. For me it is important that you are clean and quiet. I love to party, but not in the flat. There I would very much like to study. I am from Oxford but I have been living and studying in Germany for the past few years. I also would like to share the flat with friendly people. I don t mind whether you are boys or girls and I don t mind how old you are, the most important thing is that you are friendly. I consider myself as being clean, quiet and friendly.
