The room itself and the en-suite bathroom are spacious and clean. The bed was a little hard for my gf but was perfect for me! Audrey provided a little breakfast on 2 of our 6 mornings, which was a nice little something to start the day. The location is good although maybe a little out from the centre - we ended up walking for miles to get about and see everything! We do generally like walking everywhere but with the hills and the same walks back and forth it got a little tiring. The metro is not the easiest to get about to everywhere although it's only a ten min walk from Audreys, and then another two stops to Napoli Centrale railway station - from here you can get to Herculaneum/Pompeii (+ then Vesuvius) with ease. The metro is really cheap too.
The only reason we gave 4 stars was just a couple of confusing points - there was an issue with one of the keys but we were not told about it, so we came back one night and could not get in the main door downstairs (in fact there are 4 different doors to get through, all with keys). We had to ring Audrey to get in. We were then told about the key and advised to speak to her friend who worked downstairs in reception(?) to explain all the keys - I'm not sure why Audrey could not just explain them to us. And we did find the situation with the living room available. There is a picture of it included in the photos but we were never told if we could use it or not and it perhaps would have been nice to lounge about on the sofa with a takeaway pizza one night, we were just completely unsure if we were 'allowed'. I think a bit more proactiveness with information would have been good.
However, overall it was still a really nice stay and Audrey very kindly let us leave our luggage there all day until we left about 5pm, so that was much appreciated. The surrounding area is nice and 15 mins walk (5 mins beyond the metro basically) gets you to a nice area of bars and restaurants. We would definitely recommend staying here and having a nice city break.
