Meeting the person who let us in was okay. But the number you first get is a concierge for iFlat and then someone else comes and lets you in (a little confusing). But they showed up on time and it was easy.
There are quite a bit of stairs to go up so keep that in mind. We were a little disappointed with the lack of basic amenities (some extra toilet paper, any hand soap, a working fan -- there was a broken one). When we whatsapp'd the concierge number someone did come to drop everything off that we requested which was great.
We were very happy with the location, easy access to all the main attractions (10-20 min walks) and near Monti which is a very cute area. Note that it is a on a street with no outlet -- you will have to back out backwards if you drive to the door (the street is too narrow to turn around)
The place felt a little bit more run down than the photos, there were couch covers on the couch that were a little unattractive. There is AC in one bedroom which was helpful during a heatwave.
Overall an okay experience
