Frank's appartment is well located for the visits, thanks to close public transports (2 subway stations and bus lines in the avenue).
Lots of shops, and take-away food providers open until late at night. We were welcomed in these shops.
The area is relatively quiet (but first room is on St Nicholas Avenue) and secure. Just to be aware of current construction works on next building, starting 7am. Hopefully this will not last!
The 2 aquariums are a great idea and source of relaxation.
Frank was very available and flexible for arrival and departure, and willing to give advice for the visits and services.
