It was a pleasure staying in Frank and Sarah's place! They were both quick to reply to any inquiries and Frank even booked a cab to pick us up from the train station to the apartment to make sure we don't get ripped off by the taxi in Prague. The apartment itself is huge and functional, and I particularly love the big windows, there is no AC but it wasn't much of a problem because of the good ventilation, the location of the flat is the most unbeatable, close to all the hustle and bustle of Prague and lots of nice places to eat and drink in the ground floor of the building. Frank also gave us some good tips on where to eat, do our grocery and what to visit. Will definitely stay again!
