Everything about our stay was excellent, including the host's communication, but the one glaring issue was a big one. There seems to be something wrong with the plumbing or ventilation in the apartment, and the was a very strong mildew/sewer gas smell permeating the building's lobby, the master bedroom, and the laundry room. We stayed in the guest bedroom to avoid it. The host did everything they could to make our stay more comfortable, but air fresheners and de-humidifiers couldn't resolve the issue. I appreciate their hospitality and eagerness to fix the issue, but it will probably take a more extensive repair of whatever plumbing or venting issue is causing that.
