Just back from Slovenia so can write a review of Massimo's flat.
Whilst (like other reviews) the general communication could have been better everything was pretty good. For our group of 7 the one night pit stop in this apartment (en route to Punk Rock Holiday in Tolmin) was good. Yes, the general materials in the flat are basic, however it didn't matter to us really due to our length of stay.
The apartment is really big and the bathroom is HUGE which is why the lack of furniture makes it seem a little more empty than it seems.
We didn't arrive til 22.15 and the walk to the apartment wasn't far at all after getting off the water ferry from the Airport we had to wait about 20 minutes at the apartment for Massimo to arrive but his directions from the ferry drop-off point were absolutely bang on. The flat is situated in a quiet part of Venice so our catering options were limited but our host provided us a great recommendation where we could still get some great food and a few beers and it was well after 11pm. (Thanks for the bar reccomendation Massimo the vegetarian burgers were great and the homemade chips were sublime!)
If a little more welcoming touches like a few provisions in the refrigerator upon arrival and some home comforts (maybe a sofa or two) i would definitely consider coming back to the area to use this as a base for a longer stay.
One tip though if you're going back to the airport from the closest ferry pick up make sure you're not in a big group, (or if you are give PLENTY of time to get there) as we had to wait 90 minutes to actually get on one. As its the last stop before the airport they were all full. Luckily we weren't going for a flight (only hire car collection)
