We arrived late at night from the airport. There was a delay of the train but Roman's daughter was there to wait for us for check in. She was helpful to tell us the direction and attractions in Prague. She also informed us about the free entry of the National Gallery on that day.
The apartment may be cozy and artistic to some visitors. But for my mum, she's expecting somewhere clean and tidy. It was actually an art studio. Some furniture has to be fixed. The washing machine and kitchen seemed not been used for long. The toilet is shared with another apartment which is outside the room. Since my mum was concerned about all these, we actually moved to an hotel after a night staying there. But it seems like the hotel isn't refurnished well either, just a bit more neat and clean. Perhaps this is what to expect in Prague as we had no experience staying here before.
Overall, it's a good place and value for money for young adventurers in Prague. I would recommend it to flexible backpackers.
