My girlfriend & I stayed at Marek's for a long weekend in Prague. The flat was really bright, comfortable, & incredibly clean. The check in/checkout process was straightforward & Marek was both personable and responsive. The flat is a 10-15 minute walk along the river from most of the main sights and we even received a list of his recommendations prior to arrival with sights, restaurants, bars, etc... All in all it was fantastic & I'd recommend it to anyone travelling to Prague!
