Location location location! This Airbnb has one of the best locations from any other places I've ever stayed at. It's right next door to the Charles Bridge and to one of the most beautiful churches I've seen (St. Nicholas). It's also about a 10 mins walk to the castle and a 3 mins walk to the tram station. There are many good restaurants nearby, an ATM, grocery store, McDonald's, coffee shops, there's even a pharmacy nearby! The views from the apt were the best.
The apt had everything we needed for our monthly stay. We had some small issues with the WIFI but we managed to fix it. Because the Apt is next door to a busy street it can get noisy, mostly over the weekends, so we couldn't leave the window open as much as we would like to, but it's ok (it's the city center anyways!). The apt has no dryer but they have a drying hanger rack which worked great. The bed was comfy and there was a small table to eat/work.
Oh and Simona took the time to pick us up at the airport which was awesome!
Overall the place was excellent, I highly recommend it.
