Good communication with Dennis, the flat is very clean, the beds and bedding are very comfortable, and the kitchen is well equipped. However, it's not a place for light sleepers or for people who don't do well with noise, as the flat is right on a busy street and the walls and windows are not well insulated. The small bedroom with the single bed would work ok for light sleepers since it's facing the alley rather than the street, but still bring earplugs so you don't hear the neighbours.
Although apparently there haven't been issues with parties in the neighbouring flats for past guests, we were unlucky enough to arrive the night that there was a party going on next door that didn't stop until after 2am. The loud music + the insulation issue meant that it was as if the party was happening in the flat itself! Dennis was very reactive and tried to help by speaking with the city's "environment team" to try to make a noise complaint and send someone to try to make the neighbours turn down the music, but unfortunately there was nothing that could be done. He did say he would get the neighbours' phone number so he could reach out to them directly in case something like that happened in the future. (There was also music the following night coming from the street, but thankfully at least it didn't last late into the night.)
