While a negative experience overall, I want to at least mention a few positives. The apartment is in a great location within Centro Storico. Marco is very quick to respond to inquiries. Wonderful terrace for warmer weather giving two couples sharing apartment some space to spread out in relax. Space within apartment is not very conducive to two couples sharing a stay. Both bedrooms are at one end of the apartment while both baths are at the other end. So no ensuite baths which mean bringing a coverup if you have to shower at one end & walk thru apartment back to your bedroom. Cleaning was very superficial & could use a bit more "elbow grease". Plumbing fixtures in state of disrepair. One bath had a very loose faucet flopping around sink, both bidet faucets so plugged up that water basically almost didn't flow out. Shower in bathroom with loose sink faucet needs major attention. Handle to turn on shower falls off, overhead rain shower is so plugged & falling apart and shower pan leaks so there is a pool of water on floor after taking a shower. Seems like very little maintenance or care of unit is provided. Seems a bit worn. Common space with kitchen, table & couch is very small and not really suited for 4 people without feeling claustrophobic. You better bring all toiletry essentials, as no bar/body soap or shampoo is provided, along with a roll of paper towels as kitchen had none. Overall photos of space were really misleading and made apartment seem not only bigger, but in a much better condition than reality dictated. Marco needs to have someone provide a higher level of care to the unit and not be so hands off remotely from Rome.
And you better be ready for the hike up to the fifth floor. Come bearing little luggage as it's a pain to haul to top floor. Lastly, hope you aren't a late sleep as windows in bedroom are not blackout.
