I've stayed in Ana's place with a friend for 5 nights. We liked the central location, and communication and check-in was really easy. Ana was super accommodating and let us check in early and check out late on our last day, which was super helpful.
The apartment is not that small, but has a quirky layout. The loft bed was comfortable enough but it's a small crawl space up a detachable small ladder, so not for everyone. Also you can not open the sofa bed without moving the loft ladder, so its tricky as the person sleeping above can not come down during the night. The toilet room is also very tiny, but the shower room was good.
Overall it's a fine place for a quick stay and Ana is a wonderful host.
