Helena’s place has an absolutely fantastic location if you want to explore the city on foot and also be very close to nightlife. There was no noise at night but you’re right in the middle of the action. The apartment has great amenities and feels really safe. Beds were comfy and everything worked really well for a group of 5 of us. If you are vegetarian or vegan (or even if you’re not!) there’s a fantastic buffet restaurant just below the apartment (DaTerra) with vegan pastel de nata!
