We had a difficult time with this review because we wanted to give more stars, but we can't. The location is pretty good! Piazza Navona and the Panetheon are minutes away, along with great food options. We were able to walk almost eveywhere and only took a bus once when we were also doing a bike tour the same day. The first reason we took off some stars was for our quality of sleep which was incredibly poor for the week we were there. we specifically chose this apartment based on reviews that said it was extremely quiet and the bed was comfortable. We knew about the church bells going off at 7 am the morning beforehand and signed up for that, but were not ready for hearing the market below do deliveries/work at both midnight and 6 am. It wasn't just loud, but we could feel things rumbling through the entire building. The bed was also not comfortable to us personally - very firm and we woke up everyday with pain. Luckily these things are more personal, so if you're a heavy sleeper or like firm beds, then it would probably be a good option for you.
The second reason we took off a star was because we came home on our last afternoon to about a hundred ants in the bathroom. We found spray under the sink (one of the few things there) to take care of it immediately, and told Giuseppe, also requesting some new towels. He was responsive and came by that evening to clean the bathroom, treat it for the ants, and provide all new towels. We did really appreciate this and didn't have any other issues, but it wasn't a great experience.
Last thing is that some things were broken or didn't work amazingly well. The door frame was breaking off on the inside, a lot of water leaked from the shower, you had to open the refrigerator carefully or it seemed like it was going to fall off, and the closest drawers didn't work. I'm also not sure how much you could actually cook your own meals here unless it was breakfast because the kitchen didn't seem super well stocked (we didn't really need it, just an observation).
Giuseppe himself was really kind and helpful which is why it was hard to give a 2 star review. Some of these things are out of his control, but some aren't. We've had better experiences elsewhere, so this is where it sits relative to those. If you are a light sleeper who might want to cook, don't stay here. If you can sleep everywhere and just want to have snacks around, go for it!
