Room for rent for a month

I'm looking for a room to rent near Gatwick or Crawley for a month. I usually work from home, but I need to be in the office for about a month in January. The company is based near Gatwick, but since I have a car, the distance isn't a major issue. I just need a parking space. I don't need any special amenities; just a bed, wardrobe, table, and access to a bathroom and internet.
