The apartment is in a nice enough location with a large immigrant community with good links to public transport, although probably not what most imagine Paris to be like.
The Sacre Coeur was a 20 minutes walk and Gare du Nord less than 10 minutes from apartment.
The apartment itself is a good size for 2 people, although I would advise that there is no living area and the bedroom and dining/kitchen area are separated by a semi-partition wall.
The apartment is on the 3rd floor, so be prepared to climb up spiral type stairs. This wasn’t a big issue for us, as we anticipated this in advance but may not be suitable for people with mobility issues.
Overall, we enjoyed our stay at Welkey’s and were happy with the price we paid. Thank you
