I can strongly recommend this apartment: it is exactly as presented in the description and I was satisfied with almost everything.
The kitchen equipment is perfect and you can easily find everything you need for everyday life. (The only issue I have to mention is absence of the hairdryer)
The location was exactly as I desired: close to the center, but in a quite neighborhood. It's 7 mins to Wenceslas square and 15 mins to Old Town square (by foot). Nearest metro station is in 5 min. The neighborhood is really cosy, while you can find a variety of restaurants, cafes and shops.
The communication with Nikola was always easy and fast, no problems occurred.
