We (3 friends) stayed at the apartment for 1 week. The apartment is located in a not-so-touristic neighborhood, straight across the Mergellina-Station. Everything was very uncomplicated: booking, contacting the owner and receiving the key to the apartment. He was very helpful, especially when we had any questions or problems!
The apartment was exactly as described. Everything was clean. We had a double bed upstairs and a bathroom with a bathtub and a toilet. Downstairs were two more single beds and another bathroom with a shower and a toilet.
The only thing I would mention is, that it could be difficult for taller people to shower, because the ceiling is very low.
The kitchen is fully equipped: fridge, dishwasher, gas stove, microwave and dishes are available.
There is also a huge flat-screen upstairs, if the weather should be not so nice ;)
We would definitely recommend to stay at this apartment! Maybe, we would come back, too!
