We stayed in the deluxe double room (no.4), and it was everything we needed.
A really comfortable bed, spacious area to chill on the sofa bed while waiting for the partner to get ready, tv, kettle and tea making facilities (while also waiting for the partner to get ready) - fridge, great cupboard for clothes, large private bathroom and shower area, and a lot of power outlets.
And, a superb view of the Basilica Dome.
The area was perfect.
5/10 minute walk from the metro which is only 6 stops (10 minutes from the Rome Terminal) - a stones throw from the Vatican, and a 20/25 minute walk to some of the main attractions (which is perfect to walk, so you can stroll through the historic streets, pick out restaurants and catch glimpses of Rome you may not normally see using public transport)
The Colosseum is an hour walk away, which is doable - however, there is a taxi station 3 minutes away which can take you there in 20 minutes for €15 (very reliable)
Breakfast was included in our stay, however we chose to eat out due to early starts each morning and there are a plethora of restaurants nearby or wherever you choose to start your day.
The price we paid, for the comfort, convenience, time of year and location was incredible.
The staff were really friendly and helpful, would 100% stay here again.
