Lovely apartment, tastefully decorated, with spacious hight ceiling. Right next to the Colosseum and walking distance from all the other wonderful ancient Roman sites. The kitchen is ok, moderately equipped. Mezzanine level has a double bed with a quite firm mattress. The pillows were not very comfortable, felt like they had not been replaced for a long time.
The bathroom was the real let down unfortunately, hence the rating: one star off. The toilet seat was not fixed on to the toilet properly, kept moving! The bath was very old and the drainage wasn't working properly.
So, if these issues are sorted out, which should not take too much a trouble to put it right, I would definitely come back again.
