The beds (mattress) were very poor. The guests "sinked" when they were sit or laid down. We talked to Silvia but she said they couldn't change the mattress and that they have never received complaints before. We want to register our complaint so future guests are aware of this problem before booking. For some people it may not be a problem, but we were on a business trip and we needed to rest and have a good night of sleep. The rest of the aspects of the apratment were ok.
