Very clean and spacious apartment. Very close to a metro station and about a 5-10 minute walk to the larger train station. We took the metro from CGD and it worked out fine. The main streets are pretty busy with people selling cigarettes and other random things but we always traveled in a large group so never felt afraid. There is a little market nearby so we were able to buy some snacks. We also used their luggage storage center on the day we checked out which was super easy and a big bonus.
