Carla's Apartament was amazing for the price, the location is very central, its only 5 min walking to the metro and almost in the exact center of the city.
I would defenetly recomend a stay for more days because we only stayed 3 days and there was nowhere near enough time to visit this amazing city! I would recomend booking like a week to have time to enjoy the city. I already wana plan a second visit somewhere in summer or autumn.
