The place is incredible. The location is A++. You are looking at the park Riegrovy Sady from the balcony, it is a 10min walk to the main train station & 10 min walk to Venceslav's Square, all the while located in the most international & colourful part of Prague - Vinohrady.
The hosting team are incredibly flexible and nice, and will help you out as best they can.
The apartment itself is a good-sized two-bedroom flat - one of the beds is in the kitchen though. I was there for about 5 weeks and it was brilliant, though I can imagine it being good for 2-4 people, especially for shorter getaways.
You have all you need in the kitchen & bathroom with some complimentary goods here and there.
Definitely will be top of my list in case I will be back in Prague. Just super convenient.
