We received a very warm welcome, the apartment was nice and well appointed, and public transport connections are also good with bus, tram and metro close by.
The only negative points are parking could be a bit of a pain (although we parked the car on the first day and didn't move it, parking tickets weren't expensive), the area isn't the best for going out in the evening (we chose to eat in the city) and there was a slight smell of smoke in the apartment.
Overall the negative points are very minor and I wouldn't hesitate to recommend the Rainbow House, I'd also happily stay there again.
Communication with Alessandra was also very easy, and she was very accommodating to our arrival and departure times.
