Adorable and huge flat in the very center of Prague, yet in a quiet and very pleasant neighbourhood next to the river. Very spacious and nicely furbished, comfortable apartment! The beds are also comfortable, kitchen is well equipped (the Nespresso machine on the photos is not there anymore so if you're a coffee drinker, think about bringing your own coffee maker). The check-in and check-out happens in person due to the nature of the locks, but everything went smoothly and flexible. Communication was also easy and fast.
For us it was a 5 star :)
Please note the flat is on the uppermost floor of the building without elevator, so if you have difficulties with mounting the stairs, keep this in mind.
