Very easy to use the Metro to get to Rue Burg. Don't use a taxi. We bought a Paris Pass at the main train station. Have an ID picture avaliable for the metro pass, save's time rather than doing it at the station. We stayed 5 nights which was great as it allowed us time to see and do what we wanted to without having jam everything in, in 3 days.
The apartment couldn't have been in a better location. We loved it. It has everything you need. May be advisable to bring your own towels.
We would definately use this apartment again.
Seleha was very welcoming and gave good advice. Plus
