Maria's place was perfect for me. The apartment is one block from the subway station and in less than 15 minutes you can reach the main touristic attractions of Barcelona Downtown.
the apartment is very clean ans silient inside.
At nigth, maybe you can listen to some noise outside, but it's ok and not often.
the apartmentnis on tge 3rd flour by stairs, so if you have havy luggage it might be a little difficult, but it is worth.
