I had a great time in Robert's apartment, the location is perfect, you can reach train station by 10mins walk, and also very convenient to the surrounding tourisms.
The room was clean and quiet, your have your own space, and your have your own back door to leave the apartment without passing the living room which is great. The bathroom was not that clean compare with the room. Robert is really gentle and kind, I have the problem with the EU adapter and he give me one as long as he knew.
In all, if you are planning to travel alone, Robert's place is recommended.
