We stayed at Milena's apartment for 5 nights and were very happy. The apartment is perfect for two people. The apartment was clean and had everything that we needed. Milena was very quick to respond to any questions we had and the check in and check out were super easy. The apartment is located in a secure building and was really quiet, which we really appreciated. The best thing about it is definitely the location - you only need about 10-15 minutes on foot till the historic city centre. We didn't have to use any public transport at all but if you do, there's a tram line going just outside the building. We would definitely stay here again if we are ever in Prague in the future.
