A great place - highly recommend it. Really excellent hosts. Super friendly and great at communicating (including giving recommendations etc).
Very spacious apartment. Kitchen is decently well-equipped (oven/electric hobs, pots and pans, washing machine, etc), bedroom is huge, living room is a decent size and very comfortable (nice sofa), and there are separate shower and toilet rooms. And the entire apartment is decorated with very tasteful art.
Location isn't bad at all, especially considering the price - decent neighbourhood with a good boulangerie less than a minute away and supermarkets only 7 or 8 minutes' walk away. It's only a 20 minute walk to Oberkampf (lots of great cafes and restaurants) or a 25 minute metro to the very centre of Paris.
Overall, great value for money and I'd definitely stay here again.
