We felt completely welcome at Lucas' apartment. Although he was not able to meet us personally, he had Liliana there and in spite of some language difficulties, we were able to understand enough to feel at home.
The location was perfect, halfway between the "touristy" things that are always a requirement and the local scene which is much more economical and which we prefer.
Any questions which did come up regarding the apartment or how to get around Venice or almost anything else we wanted to know were quickly answered by emails from Luca.

There were a couple of minor problems with our warm water but they were fixed in good time.
Luca left us some recommendations for places to eat and shop that were terrific and he also left a brief history of the apartment which reinforced the sense of history in which we were immersed as soon as we arrived.
Small but appreciated touches were the bottle of wine that was there for us, the Visitors book left for us to sign and the already mentioned history of the apartment as well as the recommendations

Overall a terrific stay in a high quality apartment.
