Federico's place was a perfect fit for my cousin and I.
Pros:
Only a couple blocks away from the coliseum and ancient forum, which was all walking distance
Metro was very accessible and walking distance (right across from the coliseum)
Clean and tidy upon arriving
Mini fridge, microwave, kettle, and utensils provided
Safe neighborhood
Provided a bottle of wine :)
Check in was very easy and welcoming
Cons:
Although it was close to the coliseum, it was a short journey to other landmarks in Rome, such as Spanish Steps and Fontana di Trevi which was very lively all day and night! Lots of shops and restaurants in that area.
Shower was VERY tiny! We are two petite women and it was so hard for us to shower. You also have to make sure the shower curtain stays inside the metal guard on the floor so the water doesn't get on the bathroom floor and make a puddle by the toilet. We also ran out of warm water for the second person to shower.
By a busy street so the mornings can get quite loud with cars, but didn't bother us too much.
Our stay was still EXCELLENT despite these little things. I would definitely stay here again and recommend it to anyone.
