We had a lovely stay at Inge and Antonio's apartment! Especially the location was great, very close from the Pigneto district with loads of bars and sort of a 'hipster' neighbourhood, and around 45 minutes walking distance from the Coliseum. We took advantage of the weather to explore the whole city walking but could've easily taken a bus or metro which are also just a couple of minutes away from the apartment.
The apartment itself was also really nice, and had everything we needed for the 4 days we were there, including plenty of towels, fans for the rooms, fully equipped kitchen, mosquito sprays, big balcony sitting area, etc....
All in all perfect to visit Rome for a couple of days, we would definitely recommend it to others:)
