Semek is a great host. He is friendly and helpful, without invading the personal space, he keeps his apartment clean and pleasant and is ready to give any useful information. The apartment is very nice, and the room as well. The position is close to the train station and to the centre, 1 minute away from tram stops and 5 minutes away to the bus stops leading to TU Delft and to other parts of the city.
I would definitely recommend it!
