I've participated in the program twice and I look forward to doing it again next year.
It's a great opportunity to develop your language skills while still enjoying Munich and your holidays. You can make new friends with people from many different countries and continents. At the same time the school is very professional and well situated, only 5 minutes walking from the English Garden, right next to 'Lehel' underground station and also quite close to Munich's old town.
During my visits I stayed at the EF Residence in Geiger Hotel as well as in the EF Residence close to Olympia Einkaufszentrum. I can recommend both, but second one is exclusively for EF Students, which makes it a great way to spend more time with your new friends and also - in my opinion - it has better standard as it has been open for 2 months right now, so everything is new and working. Rooms are very quiet, clean and contain of a bathroom, a kitchen and one or two beds - depending on your accommodation choice. There is also a common balcony, laundry facility (€2,50 per washing and €1,50 per drying) and a lounge with a big table, sofas and XBOX One. WiFi works very well in the residence as well as at school.
Munich itself is a stunning city, not distant from the Alps and it is the capital city of Bavaria, Germany's biggest federal state. It has a very rich culture, many recreational sites (such as Olympic Park and the English Garden). There are also lots of museums, shopping centres and restaurants. Also, Munich is famous of its Biergartens (Beer gardens), where you can bring your own food (or buy it there) and enjoy the world's best beer. If you'd like to make excursions - Nurnberg, Salzburg, the Alps, beautiful lakes and historical sites are situated in 2-hours distance by train. Around Munich you can get everywhere by public transport for €21 per week.
