Olga was great! We arrived in Prague pretty early, long before check in time and went to find her office, which was right near the train station. She gave us a useful run down of the neighbourhood and recommended some places to eat. The apartment was really beautiful, very clean, comfortable beds, lovely bathrooms. It was nicely located just a 5-10 minute walk from Old Town Square, which was really perfect as we didn't have much time in the city and just wanted to get into the action ASAP. The experience was no hassle and very lovely. Wish we could have stayed longer.
