Economy awards within Europe are generally very bad value. The fees are as much as you could get a ticket for otherwise.
for 23k you can't do much even within Europe anyway. The only value I have been able to extract anywhere near that number was a one-way business class award within Europe at 25K, but that was quite specific circumstances. Consider whether that might make sense to you any time soon maybe.
Otherwise I am afraid reasonable redemptions start at around 60-80k for one.
