The location of the apartment is really nice, in the centre of Trastevere, a very nice and vivid area. The apartment was ok, but 'luxury' is a bit exaggerated I think. The room could use some small refurbishment works, for example the door frames were loose, the shower drain is clogged and the shower has a little bit of fungus. Nothing really bad, but that are some things that didn't make the room 'luxury'.
Andreas was really friendly when I called him with a question about our check in, but the communication by whatsapp didn't go very well, we didn't get answers to our questions.
The final night there were extremely loud guests in the room next to us (screaming, dropping things, tapping on the walls, the whole hall smelled like weed). We didn't sleep from 1.30 am until 5 am. The next day, we texted this to the owners of the apartment (they own both apartments). The person I talked to was very friendly and promised me to contact Air bnb to get a refund (40 euro). They told me they would let me know the day after. But unfortunately, we didn't hear from them again.
I've sent them a message myself, but never got a reaction, and until now I didn't get any refund.
