Alex and Tanya's place is in a brilliant location for first-time visitors to Prague. I would recommend it for couples, small groups of friends or families. It was totally spotless - couldn't fault the cleanliness of the place. We had a nightmare arriving to Prague (cancelled flights and severe delays), yet Alex and Tanya made special arrangements for us to picked up at 0230 in the morning, which we really appreciated!
The only thing that would have been better (this is a very small thing) would if we had been given two sets of keys on arrival, as we had to.make a special trip to Abrupt offices to pick up. Also - a tip for travellers - do to go to the local minimarket as they are extortionately expensive. Take a slightly longer walk and go to Tesco nearby. This isn't suggested on arrival, but I would strongly recommend walking for 5 extra minutes to get much cheaper groceries!
