I had a very good stay at Maxi's apartment.
He contacted me well in advance to organize the arrival and he was always very friendly and proactive to make sure everything was going well during my stay.
He also allowed for an early check-in without additional cost, which was really nice as my flight was supposed to arrive early morning.
Regarding the apartment, it is very nice and looks exactly as on the pictures.
Only downpoint was works on a close building that started early and meant for heavy noise from 8 am but it didn't prevent from working from the apartment.
