Birmy International English school is a pretty crowded place, and this isn't a bad thing. It just reflects the kind of reputation this language school has in the community as a place for excellent English education.
Kids normally come to Birmy to study English after their regular school hours. This means that you are likely to teach in the evenings. In my case, I had 2 classes in the evening (5 to 7pm). Adult students and teenagers would normally come on Saturdays because most of them are in college or are employed individuals. My busiest day was actually Saturday, and my only real day-off was Sunday.
In terms of accommodation, Birmy will actually provide you with a place to stay for free. I stayed in a place that seemed like a university dorm. There were 15 other foreign teachers there (all from Birmy), so I had a lot of people to talk to during my free time. If it's your first time to work abroad, then you would want to have friends you can talk with and visit places with. This will help you overcome any feeling of homesickness.
If you want to live on your own and have some privacy, well, you can move to an apartment that's close to the school. Birmy will even assist you in finding a good yet affordable apartment if you want.
