I 'd recommend Mariano's place to all travellers coming through Buenos Aires, especially ones who enjoy a comfortable bed, kind and responsive hosts, as well as next-level cleanliness. If smells are important to you, you will extra appreciate it here. The neighbourhood - Núñez - is perfectly safe and connected to parts of the city that you might not see if you stick to the touristy areas of BA (go to Núñez station and head north to Vicente Lopez, San Isidro, and Tigre). Mariano recommended some great spots and Rita Specialty Coffee was my favourite, just two blocks away and you can get delicious coffee and healthy yet scrumptious food (or pastries) at really good prices. Right downstairs there is an excellent chocolatier if you're feeling less healthy - they offer a 10% discount for cash purchases. Boutique de Pizzas is another great option nearby - their plum and pancetta pizza is wiiiiicked good. Ask them for delivery via whats app and there is no charge to bring it to your door - just tip the delivery guy at least 10% because you might become reliant on them like I did. Saavedra Park is around the corner to run off everything you just ate, or to laze about out in the sun, amongst the trees, and chill out with the Porteños. Anyway, great location, great hosts, recommended!
