Accommodation

 

We intend to cover bed and breakfast accommodation for participants for the three days (four nights) in the University Residence Harmonie , situated conveniently close to the workshop venue (Jannasch Lecture Hall in the music conservatorium of the University of Stellenbosch http://academic.sun.ac.za/music/facilities.html ). Harmonie is also next to the attractive Botanical Garden of the University.

 

Please note that such support will be handled on the basis of 'first come first served', i.e. we'll follow the list of applications according to the dates of first entries (using the website or by e-mail) up to about sixty participants.

 

For delegates seeking accommodation in a hotel or one of the many excellent guest houses, we suggest browsing http://www.sa-venues.com/accommodation/wc_stellenbosch.htm or any of many similar pages which can easily be found through Google.

 

Four excellent guest houses which are within five minutes walking distance of the workshop venue and the university campus have offered workshop participants special B&B rates for the four nights of the meeting. They are:

Stellenbosch

Just 45 minutes drive from Cape town lies the historical town of Stellenbosch. Stellenbosch is the second oldest town in South Africa and one of the most scenic. Its location in the heart of the Cape Winelands is in as beautiful a setting as you are likely to find anywhere.

Justly famous for its wine and fine cuisine, Stellenbosch has much to offer its visitors. A wide variety of activities await you, if you are an outdoor person the vineyards, mountains, streams and golf courses will tempt you to explore. If you prefer a more sedate experience, the many wine cellars offering tastings and sales, the fine restaurants, boutiques and historical architecture of Stellenbosch are sure to provide you with plenty to occupy your time.

The heart of the town lies somewhere near the oak-lined Dorp Street. With its venerable old buildings, this is the University´s main thoroughfare, where modern student life sits comfortably side by side with our history and architectural heritage.
