I felt very, very sad staying here. The apartment was clearly someone's labor of love a few decades back – a lot of high quality custom furniture, lighting, and even masonry went into building what feels like a former love nest. But the new owners seem more interested in milking it for money rather than preserving (let alone improving) the property. The bathtub is flaking (it's custom made), the only handheld shower head in the house doesn't work, several of the light sources are burned out, some of the wall sockets don't have power (notably one in the bedroom, where I found my phone dead in the morning), one of the doors is difficult to open, the freezer hasn't been defrosted in a million years and it's all a solid block of ice, the mattresses in the master bedroom are obviously aftermarket, of poor quality and a bad fit for the bed, and the entire thing looks and feels like a sad, unloved place.
Apart from the sad feeling of disrepair, the need to milk money from this apartment is also apparent in the haphazard way it's thought out from a practical perspective. The master bedroom would host a couple very well (apart from the issues above), but there's also a twin, short bunker bed in a separate room, presumably for small children. The practical aspects become apparent as soon as you explore the apartment (but not from the photos): you can only access the terrace via the room with the bunk beds, and the only shower in the apartment is in the master bedroom. So if you travel with at least one kid you can't really use the terrace at night, and you have to give them access to the master bedroom for showers. Ironically, it looks like there used to be access to the terrace via the building's hallway, which would've been way more convenient, but that seems permanently locked now.
Apart from these (significant) inconveniences, our experience was good. The neighborhood is very lively at almost all hours (which is very convenient when you want to go out), but the apartment is remarkably well positioned to isolate the noise outside (which is very nice when you want to stay in). Our communication with the host has been impeccable, all of the procedures were well explained, and the check in was seamless (although mind the extra charge for late check in, which is also properly explained). The host has been gracious throughout our stay. I actually feel kinda bad on a personal level for leaving this review, but it reflects our experience – and at the end of the day, that's what reviews are for.
