None of these are problems at all but I wouldn't recommend staying here for business (we didn't this time but often do)
1. General advice - make sure you have the right charger adapter but if not, there is a supermarket 50m away that sells them if needed (about 4.5 euros) and the staff do have a variety of adapters to lend
There wasn't an abundance of power sockets. I charge my phone using a remote battery and that was fine for me - if you're travelling with laptops and other devices, you may want to plan that
2. Get a white, licensed taxi from the airport to the hotel. It's a fixed fee 48 euro to within the city walls. The train / bus journey was a pain with luggage and the walk across cobbles is less than ideal
3. The wifi access isn't that fast and some sites/media didn't load. Don't rely on it for heavy use but it's fine for emails. 3G coverage was fine (O2) but as it's a busy area, it's also quite slow
Fantastic location, right next to the Pantheon. The staff are incredibly friendly and helpful.
Breakfast was excellent, though if you like a fry up there are limited cooked options. Homemade cake (always worth having!!), big pastry selection, a few cereals, lots of fruit and yoghurt, eggs and bacon, toast machine and big variety of rolls, cold meats and cheese
The shower (over bath) was strong and beds perfectly comfortable. The room was more than spacious enough (standard double) and the bathroom well equipped with toiletries. Water was more than hot enough but crucially also could be nice and cold - needed midday showers to cool off!
Roof terrace and bar is brilliant. Staff there are awesome too
We couldn't hear any noise from the piazza when inside the hotel, which often had music and noisey chatter in the evening, so had a perfect blend of entertainment and leave and quiet (our room didn't face on to the piazza though)
Air conditioning wasn't overly noisy and was effective (was 36 degrees in the sun)
Essentially it's the perfect base hotel for staying in the historic centre.
