Maintenance and communication were both significant issues. In advance of our trip, sometimes Guido replied promptly to our emails and texts and sometimes he did not reply at all. The air conditioner didn't work, apartment was not cleaned from previous guests until five hours after check-in time, a large crib had been assembled inside the master bedroom and not removed (and was too big to fit through the door). Guido's employee either didn't reply at all to our texts or replied with no solution (for example, suggested we disassemble the crib ourselves). Once we escalated to Guido, he resolved the issues and apologized. However, given that they are a professional vacation rental company, the poor maintenance and responsiveness were disappointing.
