I stayed here for an extended weekend with my family. When we arrived at the office, they staff were very welcoming and gave us some very good advice on places to visit. This apartment is just round the corner from their office (Next to the Halal restaurant). The apartment was incredibly clean and even included ground coffee and English tea which was a bonus. Its location was brilliant, a 5minute walk to Wenceslas Square. We were able to walk everywhere from the apartment. On the day of check out, we were able to leave our bags at the office whilst we had one final explore of Prague before heading to the airport. They have luggage storage freely available in the office so this was very easy. The office is only a 5minute walk to the main train station where we got the airport express bus to the airport.
Absolutely loved our stay here and would highly recommend Alex and Kates.
