The photos say it all! There is not a better situated apartment in all of Rome if you want to see the Colosseum. There are 5 windows that directly face this huge structure, and 2 other windows that face a green park to the east. As the photos show, one bedroom has two small beds, and the other two bedrooms have large beds. There are two bathrooms, both with showers but no tubs. The laundry machine worked well, and detergent was provided. Be aware that there isn't an electric dryer, but there are drying racks.
We visited in December, and it was chilly at night, so we used the furnace. Unlike my furnace at home, there isn't a thermostat. You set it to a particular level, 1-5, and it runs all of the heating registers in the apartment. We found level 1 was perfect for nighttime, and we turned it off during the day.
The kitchen is well supplied. The microwave looks like it might also be an oven, but we couldn't figure it out, but didn't really need it. We ate 2 meals a day in the apartment, and we are a family of 6. So while the kitchen is tiny, it works! The market is just a few minutes walk away.
I cannot recommend this place enough. It clearly has an unbeatable location in Rome, is well furnished with antiques, and is very livable. It does stay noisy at night, with tourists visiting the Colosseum, but that didn't bother us. We hope to stay here again!
