We had such a wonderful stay at Melissa's centrally located apartment! Everything we wanted to explore for the first few days in Barcelona were walkable from the place. It wasn't an issue at all for us, but if you are a light sleeper you may want to bring a pair of earplugs as it is a lively street into the evening! Although we didn't spend too much time in the place other than sleeping, there is wonderful light in the early afternoon that pours in from the windows which we loved.
Melissa was such a wonderful host & the next time we are in barcelona we will surely be back! 10/10 recommend!
