I have been in about 10 b&b in Venice last year, so i might have a view...
In summary:
- Rachele is professional, kind, perfect english
- great location, quite and near Rialto Market
- flat is pretty large even if with just one bedroom
- flat has basic amenities, asked for something to press orange juices .. did not get something i was able to have in all others, a minor point but did not like it
- unfortunately i have been 3/7 days without heating/hot water; she intervened fast but issue not resolved
- the customer service seems tuned to high volumes with limited flexibility
- considering value4money, there are better options ...
All those could be easily improved reducing price, increasing amenities and with a more flexible approach...
