We definitely loved staying at the apartment, and our guests all said that this Airbnb felt like a cosy home. It is definitely a great option for single travellers and couples alike. It also has a large expandable couch if you need a friend to crash on the couch.
The bathroom has heated floors, which a very welcome luxury during Czech winters since the room doesn't build up moisture over time.
It won't be an issue for many, but we do find apartments with electronic-only number pad locks for the main entrance being a uncomfortable security choice. I understand that it is an easy way to check-in your guests, but it would be very appreciated if a separate set of keys was present inside the flat for the second door lock or, at least, if the door could be locked with a regular (non-electronic) lock from the inside. I think the absence of traditional locks in Airbnb's is going to be a dealbreaker for us in the future.
