Hi Monica,
I will have a room available in my apartment from September. There is a Canadian girl that currently occupies it but she'll be leaving at the end of August.
Apartment is fully furnished and has two bedrooms (so one flatmate, me), two bathrooms, open plan lounge, kitchen and dining areas, cable tv, balcony with nice view of surrounding suburbs and security.
The apartment is in Ntinda, which is not too far from Makerere, about 10-15 minutes depending on how you choose to get there.
$300/month and includes all utilities.
Cheers
Ben
