We spent a month at Vinicius'. 2 teeangers & a couple.
First, what you see on the pictures is what you get.
Nice charming typical Parisian flat, overseeing Beaubourg.
The neighborhood is very central, nice restaurants, grocery stores, boulangeries and shops at walking distance.
No vis-a-vis as you enjoy the Beaubourg plaza, no cars driving by as location is pedistrian, so it is pretty quite for Paris.
So, yes there are some stairs, yet nothing rare in Paris.
Once in the apartment, you feel well. High ceilings, clean, ready for you to settle in. The kitchen is equiped for daily meals. Don't plan to go for sophisticated meal preparation there, yet you will find enough to cook on a daily basis.
Bonus is that all the basics where there ( tea, coffee, salt, pepper, olivie oil...), as for cleaning products.
Bathrooms are efficient, with all products one might need.
Beds were comfortable, and curtain brought a great darkness.
Last, communication with the team was very smooth & reactive.
