What Carolina's studio lacks in local character and color, it makes up for with its good location and value. Communication was seamless & expedite, even when we were asking for late-night food recommendations—which, by the way, were spot-on! Checking in and out was a breeze.
We didn't get to spend much time out in the terrace, but figure it would be great for sipping on vinho verde under the (huge) Porto moon.
Ps: We were very thankful for the elevator… check if the other properties you're considering have one!
