The only complexity was obtaining all of the details of the stay. They sent a link to a Google Drive with 6 PDF files detailing getting to the place and opening the door. I had to call to ask them to send the link after I emailed a full copy of my passport. They have some laundry facilities (a washer, no drier) but you must provide your own detergent. I only stayed one night, so had no time. Definitely could accommodate 4 travelers; I was there by myself. The interior was great.
