We had a wonderful stay at Vendula and Martins apartment and cannot recommend it enough. Our train had some delays coming into Prague but Vendula was very patient and communicative, and met us personally at the apartment to show us around. The apartment was in spotless condition, everything worked, and there was even some food and drink in the fridge to get us started. The apartment is conveniently located next to a tram stop that goes directly into the center, and there's even a small supermarket nearby.
Overall we had a fantastic trip and very much recommend this apartment.
