Mario’s place is located right on la rambla & in a wonderful area. You are close to everything, and don’t worry about staying on the main street- the apartment was very quiet. I didn’t have any major issues during the stay, but Mario was always super fast to respond and help us out if we needed anything. The place is perfect for 1 person or a couple - there’s plenty of room. The apartment has everything you need and more - even throws and an umbrella. WiFi worked wonderfully throughout the 3+ months I stayed here. I would definitely stay here again if I come back to Barcelona :)
