I highly recommend staying at Federica's appartment. It's situated perfectly - just next to M1 red line. You can get easily everywhere and in a short time. There are supermarkets nearby, bars, cafes and restaurants. It's close to the city center so you can use Uber as well and you won't go bankrupt (we tried:)).
The appartment itself is great - new, bright and clean. You don't have to take towels with you, soaps or hair dryer - everything is there. It was really nice to go back there after a long day of sightseeing.
Federica is very patient host! We changed our arrival time several times and she was still able to make it possible. She's online and available all the time.
Thank you for a great stay!
