Thank you to Tereza and family! Everything went smooth and we felt very welcome. Great flexibility with check in/out, even we had to change arrangements due to problems with flight. Tereza´s parents welcomed os very nicely, there was even a little food so that we didn't need to go out and find some late evening.
Only "downside" for us, and I only mention it here, because it might be of some importance for others too: The beds were too soft for us, but that is more a question of taste and sleeping needs and not a fault from our hosts' side in itself.
Thank you so much for everything!
