This is a list of a few hotels/pensions in the Karlin area, all within a half a mile from the venue
(also Prague Hilton is in the range, in case your grant can afford that).
As I pointed out in one of the letters, Prague city center is not too large and public transportation is very good,
so you need not to restrict yourself to Karlin when looking for an accommodation.
