We did a VERY spontaneous visit to Venice and Francesca was flexible enough to quickly arrange the apartment and answer our questions on such short notice. (We booked on Monday and came on Tuesday) We came as a family - two adults and two kids aged 13 and 11.
The apartment is easy to find if you have GPS on your mobile phone. It is located in the perfect area: close enough to the hustle and bustle of the city, but in a quiet street, the bedroom directly overlooking a side canal. (Tip 1: Conad is the supermarket just around the corner and its open till 9PM. GPS was not very precise about it: You go out of the apartment to the canal, turn right and take a right again, go over the bridge, after that stay leftish, there it is.)
The interior was very stylish (our taste), everything was clean and functional, the view out of the bedroom window was beautiful, the beds were comfortable.
The kitchen had (almost) everything we needed. (Tip 2: if you like Coffee in the morning, you either have to go out and buy one, bring your own espresso maker or bring your own coffee filter from home. There is a German-style coffee machine in the apartment, but no filter. We looked for filters in all supermarkets around - nobody knew what this type of filter is!)
Tip 3: if you are using the vaporetto (water-bus) to get around Venice, this might be a useful bit of information: Guglie ist the closest station (line 4.2 or 5.2), but if you want to go sightseeing on the grand canal, you can easily walk to the station San Marcuola-Casino and take the line 1 from there. (The lines 4.2 and 5.2 were on strike the day we arrived, so we took the line 1 to S.Marcuola, which also worked out very well.)
We had wonderful, relaxed 3 days holidays in Venice and much of it was due to the beautiful apartment. We would book the same apartment again!
