Cleanliness, Communication and Air Conditioning are all negative issues for this apartment. Mold and mildew in both bathroom showers. It was so bad that you didn't want to take a shower. However, it was a must to wash off the sweat from the hot apartment. In trying to communicate with the host, it usually takes several attempts before you receive a reply. The so-called air conditioning is basically non-existent. They have one small wall unit mounted in the living room/kitchen which doesn't even cool that area. The bedrooms were extremely hot and uncomfortable. We sweated all night long and it was very unpleasant. When we alerted co-host Alex of the problems, he didn't offer to resolve them. He replied with an email, in which he told us to "pack our bags and go away".
