We stayed in Marcos place for 3 nights while in Rome and it was very affordable and close to almost everything (Termini, colloseum, and the trevi fountain area). It is a bit small, but I think that gives you the real Roman flat feel, which was cool. The entire flat was very clean and well maintained. Our only complaint wad the hot water is a little finnicky. Additionally, we got coupons for a free breakfast (coffee and pastry) at a shop right in the square, which was awesome!
