Bauer Hotel in Venice
 

I have booked 1 Superior Suite for this hotel, is this suite possible to accomodate 4 person(2 adult & 2 teen)? Thanks for your input.

The answer lies with the hotel,surely you told them how many people are in your party.If not you may have a problem.Call or e-mail them.

yes, regardless of what you booked, you have to check with your hotel about how many people can be accommodated.
Are you staying in the Palazzo section, that's more atmospheric?

yes, I emailed the hotel several times with no reply!

Call them.

Actually, I suggest faxing, so as to get a written confirmation if you don't get an email to print out

Frankly, I don't see any "advantage" to faxing them anything if they don't respond...so you've got a copy of a fax you "sent"....you get that with any e-mail you send, too.

I think this may be the time for an actual phone call.
