We are regular guests in Venice, and this one was our favourite apartment so far.
It was really close to Biennale, on a main street, so it had really nice view and it was very close to Coop (shop), it was warm, clean, well equipped, and last but not least - Oscar was a perfect host. Really nice, always there for you, but yet not intrusive. He was waiting us with umbrellas (it was raining), helped carried our luggage, and he let us stay 'till the end of the last day because he did not expect any other guests the next day. Also, the checkout was smooth, we just locked the key inside and left - no additional coordination needed.
So, we recommend and we will probably visit again.
