My girlfriend and I stayed in Filip's place for 4 nights. The apartment was great and exactly as advertised, it is perfectly located for a couple staying in Prague. The apartment is practically on top of the Charles Bridge and very close to good restaurants ect.
The apartment itself was extremely clean and cosy and is very modern (we really liked that it had smart TV, so we could watch Netflix and such when not exploring Prague). It is also very quiet at night.
Filip was a great host, he met us at the closest tram stop when we were unsure of the location of the apartment and when I closed the door with the key inside he came and opened the door for us straight away!
We would 100% recommend this place to any couples looking to stay in Prague.
