Marco is an excellent host. He was really flexible and even arranged a transfer from the airport.
Marco is an upbeat friendly chap who did a great handover. He recommended some places to visit and eat and honestly every single place we visited from the list was simply incredible.
The flat was great. Clean, tidy, airy and cool (it was 35-40C outside). The pictures to the apartment are accurate, we actually felt it was bigger in real life than expected.
Location is epic! You can literally see the walls of the Vatican and Castel Sant'Angelo from the window. There are a handful of handy shops within a few minutes walk. We walked everywhere and just explored, everything is within 30 mins.
A few reviews mentioned ambulances and noise. Honestly we barely noticed. There's a hospital close, but even the sirens in Rome are polite. We really didn't feel it was a problem.
The bathroom did have some mould, but its a very humid country so no unexpected.
If I'm being really picky I'd say change the shower head on the shower as it kept falling - but honestly really not a big deal.
The washer/dryer was extremely useful. (Tip: use setting 10 for a quick wash). Translated instructions can be found online.
We'll definitely look to visit Rome again and hopefully stay here again.
