Leonor was a charming host and her flat is in a great location with all new fixtures. She greeted us warmly and showed us all around. We noticed a smell of mildew when we walked in, but it had been raining that morning, so we were hoping that it would dissipate as the day went on. The flat is nicely furnished, and the building is beautiful. It is on the ground level, however, and the two large windows open directly into the alley where people are walking. It's not a very busy alley, but there is some foot traffic right outside your windows. We were hoping to air the place out, but whenever we opened the windows, curious pedestrians would be staring right into the flat! When we went to bed that night (comfortable beds!) I noticed that the headboard was the source of the mildew smell. When we looked behind it, we discovered that it had several patches of mold. The flat is next to a building that is being renovated, and we wondered if maybe there has been some water damage behind the wall. We moved the headboard into the other room and slept as best as we could. The next morning at 8am, the construction began next door. We are both somewhat sensitive to mold and mildew, and we both awoke with headaches. The construction noise did nothing to help our heads, and we decided to leave a day early. I brought our issues to Leonor's attention, and she was very surprised and apologetic. We felt bad for her because she is so nice, but we couldn't spend another night there. If she can take care of the mildew issue, and the construction finishes, she will have her lovely flat back again. We wish her well in the future.
