This location is amazing! On a very popular street so people are always around and felt very safe. You couldn't be closer to Charles Bridge or the Old Town Square! 5min walk to either. It is a very touristy area, but quieter/cheaper/local restaurants and pubs can be found even a street down near the university, also less than a 5 min walk.
Our check in manager was awesome, very quick to respond and schedule a driver from the airport (recommended the streets are very difficult to navigate for the first time). She was always available for questions and responded quickly. The apt itself is great, has everything you need (laundry detergent, drying rack, hair dryer) and very clean. It's also huge, the value is amazing for the location!
