This apartment had significant mold/mildew on the mattresses and bedding. I took photos of the mold on the mattresses on the two beds, located in different rooms. It appears to me to be black mold. Since it is a basement apartment, my guess is that the apratment flooded and the owner has not replaced the furniture/mattresses/etc. The stone ceiling also has mold/moss growing on it in one section. Apartment had such a strong mildew odor upon entering that we had to leave door open and fan going. Given the several fans and large dehumidifier in the apartment, I think the host is aware of the problem yet continuing to rent the apartment. Host did not appear when we checked in, rather sent a non-English speaking friend. She did not respond to any of our text or phone calls. After staying one night, we were forced to find another hotel room for the remaining two days of our stay in Riga, at significant added expense to us. We have still heard nothing in response from the host though I requested to discuss it with her. I RECOMMEND YOU DO NOT STAY HERE, I FEEL IT PRESENTS A SIGNIFICANT HEALTH HAZARD!!
