The stay at Antonio's was great. The place is cute, clean, tidy, well equipped, spacious. In winter it's a bit cold, and I can imagine in summer it might be a bit hot, because the only way to control the temperature is a small air-conditioning unit that serves the whole space (which is quite big, since it's a loft with no walls). I've found it fairly priced - not a bargain, not excessively expensive. The position is great, an Antonio was lovable. Definitely recommended if you're not on a super tight budget!
P.S. the "Real Private SPA" is a single-person sauna and a bathtub with an add-on that makes it sort of work like a jacuzzi (kind of?). I'd say it's a clickbaity title, it'd be fairer to describe it as a single person sauna and a very pretty and quite comfortable bathtub. But that's it. SPA is a bit excessive in my opinion.
