Not quite the "luxury" it seems.
When you first come in to the apartment, it's very wow! Lovely high ceilings, huge windows, wooden floors. It's in a great location - 15 min easy stroll to the Vatican, supermarket and little bars at the top of the street, metro close by - a really nice part of town. It has a little lift which was great for our group that included grandparents and kids, as the apartment's on the second floor. It has AC in all the rooms which was very welcome as Rome is hot, plus the street can be noisy at times and the windows are pretty great at keeping the noise out at night if they're closed. The apartment's arranged in an L-shape which means everyone has enough space to spread out as well.
Here's the kicker, this lovely apartment hasn't been maintained well. It's run by a company who appear to do the minimum to keep it ticking over and rented out. The basic problems you'll face are things like there aren't enough mugs or glasses for everyone. We ended up with a bit of a rota to make sure everyone could get their morning caffeine fix. A quick cheap trip to Ikea would sort that out. The sofa can only fit three/four people. Everyone else has to sit on the floor or on dining table chairs. Not very comfy especially after a day of walking and being out in the sun. More importantly, there's an issue with hot water. We had cold/tepid showers every single day and ended up boiling kettles of water so the kids could have baths. The water pressure is also pretty non-existent and the shower is ancient. We asked repeatedly about this but it was never answered. Having hot water is pretty basic, even for the most flea-ridden down at heel place, never mind for a place advertised as a "luxury apartment".
As parts of the kitchen and bathroom have broken over the years, instead of removing or replacing, they've been patched up or just left in place. For example you have to shimmy sideways in the second bathroom to fit between the toilet and now defunct bidet to take your icy shower. The shower tray also didn't drain properly just to add insult to ice cold injury. We asked them to come and look at this, but heard nothing back. We also had an issue with the outside shutters in two of the bedrooms and kitchen for the duration of our stay as they wouldn't open. This meant no fresh air or light in these rooms. We asked repeatedly for someone to come and look at them, but nothing. They eventually said it wouldn't be done during our stay as they needed to remove them, but seeing as no one visited the apartment to see what the problem was, we're not sure how they would have assessed this. Hmm.
This certainly isn't the most expensive apartment you can rent in Rome, but it's also not the cheapest. The stuff that's wrong with this apartment is so easy to fix, but looking back on other reviews, the method of fobbing you off until the end of your stay, knowing that the carefully shot and now out of date photos will entice others to book it anyway, seems to work. It is in a nice neighbourhood and has plenty of space, but being able to take a hot shower and not having to share a glass at dinner should also be a given.
Would heartily recommend you think twice before booking this apartment, which is a shame.
