We had an excellent stay in Prague. When we arrived, we were told that the apartment we had booked had a plumbing issue, so we were reassigned to an alternative apartment which turned out to be as nice, if not nicer, than this one! It was clean, spacious, with very comfy beds and useful amenities like a hairdryer, washing machine, coffee machine + coffee!
The location was great - everything was a short walk away, including some nice places to get food and drink (we didn't need to use public transport at all during the stay).
Alex and Kate replied to any queries straight away, and were very friendly and helpful, including letting us print out some coach tickets in their office.
Overall they were great hosts and I'd be very happy to book with them again and recommend them to others! :)
