We had a lovely stay on Guesthouse Libeticus. Simona helped us with all our needs, and the quality of the rooms is really awesome.
We had a small situation with the shower plumbing but was fixed in the same day after we communicated.
One thing could have been better communicated since the beginning: For the towels to get changed, we have to leave them in the floor, but no big deal! Just standard "hotel" procedure and the clean service is every other day.
Also, breakfast is nice and a relief not to look for a place to have coffee everyday :)
