The apartment is very clean and comfortable for four people. It is on first floor so it is easy to access. Metro and tram are about 10-12 minutes walking distance away and they will take you to many major attractions. Maura provides bus, biking and walking maps of the city and they are very helpful. Grocery store and restaurants are a few minutes walking distance away. Maura very quick responses to our questions. There are many taxis and it is not difficult to find one. But some of them asked 29 euro from Colosseum to the apartment (at day time of a working day) while it only costs 7 euro if it is metered. So please make sure you have an rough idea of the cost before getting on a taxi if the driver asks a fixed price.
