While the flat is new and modern, there was no air conditioning as advertised. I notified the owner the evening we arrived and did not get a reply. I notified them again the next morning and the reply was that the air conditioning was controlled by the building and there was a problem with it - they were working on resolution. I contacted them again later that day and was told it was an issue they were trying to resolve. I stated very clearly that it was too hot to sleep in the loft area, and they offered the use of two fans that we already found in the flat. As there are no windows in the loft, there is no outside ventilation and the fans were of little use. As my family and I could not sleep there, we left one day early and moved to a hotel. After we advised the owner we left early due to the lack of air conditioning and the excessive heat, they stated that they would have brought a portable air conditioner. The offer was made after I told them we left. This unit does not work for anyone who cannot tolerate 85 degree heat in the sleeping loft. Also, there is a strong unpleasant odor in the apartment. This could have been a great place to stay, but the landlord did nothing to accommodate our complaints about the high temperatures.
