One Bedroom Apartment

My girlfriend and I are Irish and both teachers. 
We are moving to a Madrid at the end of Aug to start school in Sep. 
We will be over in Madrid at the end of July/beginning of Aug to look for a one bedroom flat.
Preferably we would like somewhere quite close to the city centre.
If you think you know someone with a property or have one yourself and will be available at that time for a viewing, please send me an email. 

Thanks
