I stayed at Reda's apartment this August. Wow is that terrace a big selling point! It's arguably the biggest room in the whole house with two hammocks and outdoor furniture, so perfect for reading and relaxing away from the hustle and bustle of the city.
The building itself faces the square at Adolphe Chérioux and there are restaurants, supermarkets, and cafés all around. And even better, the Vaugirard metro on line 12 is 30s away on foot, so the rest of the city is quite accessible too. I was very comfortable here, able to cook quite a bit for the week thanks to a kitchen with all the basics, and able to work remotely from the comfort of the living room - there's a table and also a desk if you so choose. However, I think the biggest selling point for me was communication with Reda - it was extremely fluid, he's very quick to get back to you, and he cares quite a bit about how your stay is going, so he reached out more than once to check-in and make sure all was well. Overall, I'd recommend to anyone looking to experience the heart of the 15th arrondissement!
