Great stay! The room is very spacious and the whole apartment is nice and clean. A nice artistic vibe in this old building! There was no lock in the room, but you just need to trust your flatmates. There is a restaurant in the same building and it got quite noisy on Friday and Saturday, so if you are a light sleeper, bring earplugs with you. The location is good, about 10 min walk to Wenceslas Square and 25 mins to Old town square. The area felt safe. Veronika and her friend, who let me in, were very friendly and welcoming. There were many guidebooks and maps in the room and Veronika was also very helpful and answered promptly everytime I had something to ask. Very good experience!
