It was an interesting experience just to get to the office for the keys and introduction information. Tiny elevator and we were unsure of correct location cut to small sign. Olga was helpful with info and explaining the 4 keys needed to get into the apartment. We definitely felt safe. No question about that. Before we booked we made sure there was an elevator since its on the third floor. One of our travel partners has a heart condition. We were assured it did. It was broken the entire time we were there. We struggled with all the luggage up 6 sets of stairs!! And everytime we went out so we tried to plan our days so we only did them twice a day. I complained to Olga & Emil but was never fixed. The apartment was Great though and as described. Well equipped. Get very detailed written instructions for using local buses. Its very confusing and not so easy knowing where you are always. Emil and Olga did respond quickly when called but not with clear instructions at times. We required help one day several times due to getting lost on the tram system. Took us over 2hours to finally get back. Sites and costs in Prague can't be beat! Beautiful . . we used Toursbylocals and got such a great tour using Jiri Cerny. We had a great 3 days there despite our frustrations at times.
