Overall, we had a good experience and enjoyed our stay at Robert´s place.
+ The location is great, we could walk to many attractions and the nice park is very close. Many nice restaurants and supermarkets nearby (not only the "tourist ones"). The apartement is really very spacious and well equipped. Robert was friendly and helpful and allowed us to check in a bit earlier. The check in and check out was easy and practical.
- Although the apartement was newly renovated and furnished, and on the first sight everything looks very nice, we realized that there are many details which were not really though of and made the usage sometimes impractical - e.g. the glass door to one of the bathroom is too big and thus it is not possible to close the door properly. In the other bathroom there was a mold in the shower and the bidet did not work properly. In both bathrooms the water pressure in the shower was very weak, but maybe this is something common in Rome. Anyway it caused that using both showers at the same time was almost impossible.
I would recommend this place as the location is really great, Robert is friendly and helpful and there is a lot of space and equipment. I mention also the details we did not like, as I believe it would be really worth to resolve them- It would make the overall experience amazing.
