Great, modern apartment in Belleville. It's romantic, lively neighbourhood, full of cute little restaurants, bars, cafes and a canal. The flat is perfectly located for travelling pretty much anywhere in central Paris (5 min. walk from one Metro station and 10 min. to another), 5 min. to local Boulangerie with fresh baker's goods and also 5 min. to local Lidl. Most importantly for me it was with direct tube connection to the Paris Philharmonie and 15 min. on foot to Le Marais district.
Apartment itself was modern, with lots of storage space, large, comfortable bed and all amenities neccessary even for longer stays, like ours, around 10 days. There was even a bottle of whisky left for guests to enjoy as well as some nice toiletries.
We didn't have an opportunity to meet Janus personally, however, whenever needed he was always there to answer promptly all our questions. Also the receptionist was lovely and helpful.
