Ok, here's the story. This place isn't perfect. The bed wasn't great and it was noisy (the bed not the apartment), the toilet is nowhere near the bathroom and the kitchen is a bit limited. Having said that, the location of this apartment is so good that it completely makes up for these minor shortcomings.
We found the apartment very quiet at night even though it is in the middle of Croix Rouge, a busy area full of restaurants, bars, boulangeries and more. You are a 5 minute walk to the nearest metro station which connects to everywhere you are likely to go or you can walk to most places. We recommend the metro coming back up the hill. But, for us, most important of all was the amazing market on every day except Monday just a couple of minutes walk away. Fruit and veggies and most other foods available fresh every morning.
We enjoyed our stay
