Salvador is a great city and I'm sure you'll have a great time here.
My apartment is located in a familiar place and close to historic places in Salvador.
It's a 10 min by car to the most popular and beautiful beach in town, Porto da Barra. There's a supermarket, pharmacy, bus stop and restaurant just 2 mins walking.
The apartment is 2 bedrooms and 2 bathrooms, ideal for 4-6 people. There are a living room, a dining room, and a kitchen.
Also, it's a very quiet place.
