This is an absolutely beautiful flat. There's a real grand, majestic quality to the place - the kitchen is enormous and well appointed, the ceilings are wonderfully high, the bedrooms a wonderful spot to retreat, and the living room has a delightfully relaxing vintage lounge feel to it. The flat was just 10 minutes walk from where the good restaurants of the city are (Vinohrady) and about a 25 minute walk into the centre of town. Nice to get out of the noise of the city in the evening, though a few cars do pass by from time to time. Furthermore, Sofiya was a terrific host. She was more than willing to give recommendations (do ask her), and checking in was a breeze.
Sadly there was one contentious issue - which I see now that a few previous reviewers have also mentioned - in that there were extremely loud construction/building works taking place in the flat next door, resulting in being woken up at 7am by drills and hammers. It would've been good to have been told about this in advance - I've suggested Sofiya considers this for future customers - though fortunately she was very understanding about it and allowed us to check out early.
A beautiful place and host, though be wary of building works if you're a light sleeper or plan to sleep a lot.
