The apartment was lovely. It was clean, spacious and beautifully designed. The location was perfect, it was nice to be a little outside of Prague city centre where it was much quieter, but at the same time had lots going on in its own right. Karlin was somewhere I'd probably not have gone to and it was a cool area, full of cafes, bars and restaurants.
Tereza and friends were the most helpful hosts I've come across. Nothing seemed too much trouble.
I would 100% recommend and would happily stay again...
