quiet room wanted in Prague 7,1,2 or 3

I'm a mature student, sociable and responsible who's returning to prague to study and do some part-time work until the end of June 2016. I'm looking for a quiet place where I could study in the mornings. Ideally in Prague 7 but anywhere central would be good.

I've studied intercultural communications and teaching languages. I can teach English and I'm a musician although I don't play at home! I'm a good cook but very easy-going and used to sharing so I tend to fit in with flatmates' routines.

I will be working in the afternoons and evenings during the week so will be out much of the time.

I used to live in Prague years ago so I know the city well and can manage all the usual practicalities.

If there's anything you want to know, just ask me. I'll be in England until mid-September and will be staying in Muzeum and afterwards with friends in Prague 7 until I can find a place.
