My family stayed in Tania's apartments in June 2013, for 4 days. We actually stayed in Apartment 2. This is one of the most beautiful apartments that we have stayed in. It is close to the Old Town centre with tasteful modern decor in a stunning historical building. It is immaculately clean and well presented. The rooms were large with a well planned kitchen and bathroom, that could easily accommodate two couples or a family group. Tania and her colleagues are very helpful and are always available to answer questions. I would strongly recommend Tania's apartments to anyone travelling to Prague and would stay there again myself.
When you do visit, the coffee bar downstairs is a great place for a quiet evening drink.
