We absolutely loved our time at this fabulous apartment! Newly and stylishly refurbished, spotlessly clean and with lots of lovely touches like coffee, oils, soap etc provided, I would not hesitate to recommend staying here. The apartment is bright and spacious and being on the 4th floor (there is a lift) and overlooking an internal courtyard, quiet. There are a couple of good supermarkets nearby, one of which is open to about 10pm so useful for stocking the fridge upon arrival. Definitely worth eating at local restaurant Vecchia Roma, but I would recommend booking as it's very popular and there tends to be a queue of people hoping for a table.
Andrea, the host, is a fabulous communicator, nothing is too much trouble and he provided us with great tips on good local places to eat, travel and other general tourist info etc.
The apartment is in a good location for access from the airport, Termini station is just one stop away on the Metro and the apartment is also close to easy transport options to all the tourist spots you would want to visit. The Colosseum, Palatine Hill and the Forum are close enough to walk to, approx 15 minutes - it's worth booking online to visit these (and other museums etc) in order to skip the queues (even in February) and ignore the many tour guides who will try and get you to upgrade your tickets.
Next time I visit Rome I will definitely be looking to stay at this apartment again although I suspect it will soon be booked out, it's that good!
