The only thing I deduce from your comment is that maybe you are Blind? The dehumidifier is standi just in the middle of the livingroom, and cos it'a loft..of the apartment. So don't sse it it really impossible.
Plus we have 2 different A/C machines , also very useful, if like you , are allergic at a ittle of humidity.
I say allergic because this summer I had about 20 guests, and nobody complains about umidity, I mean, one wrote that is a bit humid, that is natural because you are at gorundfloor inCagliari city , on the sea, but they slept all very well and loved very much my suite.
Anyway , next time, learn to talk, you had to tell me suddenly that you felt no good and I should told you to use the deumidifier, the A/C etc etc.
You did'nt tell me anything, and now you write this orrible review, very nice of you.
I have a suggestion too: go asap to a doctor to treat your allergy....
