We had a great 2 night stay at Alex and Tanya's place. Location of the office to pick up the keys and to leave luggage was conveniently located near Mustek station which is on the super easy route to the airport by public transport!
The apartment was huge and well equipped! WiFi was very good. Beds were comfortable as was the sofa. Location was excellent, few minutes walk to the clock tower and easily walkable to all the main tourist spots. There are shops, bars and restaurants all very close by. There is a fairly big supermarket a couple of minutes walk from the apartment which was very handy!
The only problem we encountered was the noise from the street below on the first night (Saturday). There was a lot of loud singing / shouting / arguing / swearing which we struggled to sleep through as the windows were not very sound proof. However, considering our close proximity to the centre, it is to be expected. The next night was absolutely fine. Obviously this is not something within the control of the apartment owner, but useful to note as 3 of the 4 sleeping rooms are street facing.
If we return to Prague we will definitely look to book Alex and Tanya's place again!
