Boy did you ever come to the right place to find all of your answers... next to going directly to my website that is...
Okay. Where to begin.
1. Some of the slower months are July, August and January.
2. There are one month Teaching English as a Foreign Language (TEFL) courses as well as CELTA courses for confidence building and teacher training for 1000 to 2000 euros. You can find definitions for each one of these easily enough on-line if you are interested in either one.
Yes. Summer is a great time to do this teacher training and get your official certificate if you feel that you need it. Just remember that In Madrid the demand is so high that if you feel confident enough you can find jobs without having one. Simultaneously, the supply of both qualified and unqualified people who are willing to teach English is very high as well which keeps the prices people are willing to pay low. Less than half the hourly wages in Korea or Japan for example.
Anyway, certification is good for structure, confidence building, and required for many of the better, higher paying, English teaching jobs outside of Spain.
Also...July and August are great months to find long term housing in Madrid as there will be better offers than in September/October or February.
You would do best to take a
short term flat / hostal 2 weeks to a month durng July and or August and really have a good look at the places in person so that you get something not only at a good price and location, but something you will be really happy with for a whole year if necessary.

accommodation sections of my
