We , family of 7, had a great time at Sylvia's place. Everything worked out perfectly.
The location is central but in a very nice, relatively quiet area but close to the Metro and bus/tram services.
There was a heatwave whilst we were there so it was great that the place had excellent air conditioning.
The accomodation is very well laid out, modern, spacious, fully equipped and spotlessly clean. The wifi strength was also good.
There are three floors (which can be separated into 3 smaller distinct apartments) and each has its own bathroom/kitchen and living area. The sound proofing is also excellent so if you were using one or two of the apartments at the same time as someone else there would be no problem.
I guess the only possible downside would be that for older people the top floor involves climbing two flights of stairs.
Sylvia was a perfect host and gae us a very nice welcome pack including snacks, drinks and wine which was a nice touch.
We would recommend Sylvia's place in the highest possible terms and will definitely stay again if we ae ever back in Milan
