This place is very well located. It is near the central train station (where there are the bus stations, even the one for and from the airport); and is near to the National Museum. The subway is very near and that is very good mostly in the evening after a full day of walking through the city.
The neighborhood is quiet, outside of the too noisy places. Nearby there are very good places to eat breakfast (for a good start before a day of visiting).
Pavel was a very good host. He even came to the train station to give us a ride to the apartment!
Furthermore, he was gentle and helpful: he gave us a lot of information from where to change money to where to find cheap supermarkets.
