Lubos is one of the nicest people I have ever met in my life. He received us with a smile and politely explained the workings of the house. We noticed that his desk was full of notes left by people who had stayed earlier in his house. Each and every one of them said they wanted to come back to Prague, specifically to his house. On the 2nd day of our stay, I misplaced the keys to the house. He came to the house with a new set of keys within 15 minutes after I called him! Even though he had every right to be angry with me for losing the keys, he just asked me to enjoy the rest of the vacation instead of worrying about the keys! His response to other requests were also quick and efficient.
The house is located in a quite neighborhood and looks much better than the photos suggest. Also, the kitchen was fully-equipped and well-stocked. All in all, we had a good time in Prague and it would not have been possible without Lubos's hospitality snd kindness.
