Mariapia was lovely, the room was on the 4th floor, the room and kitchen was basic but everything was clean and tidy. Location right next to Garibaldi station which was ideal for us but be aware the area a little dodgy and we didn't feel very safe. Unfortunately communication with directions and actually getting into the apartment wasn't given to me prior and we spent 45 mins in the courtyard trying to work out which stairs to go up as there is 3 different stair wells, We ended up in another random B&B who luckily let me use their wifi to contact mariapia, she had then sent the number to buzz at the enterance but I received this too late :( after all that, we had no problems, the place was good for our short stay in Naples.
