Vă mulţumim pentru solicitare şi suntem bucuroşi că aţi ales hotelul nostru. Din nefericire, trebuie să vă informăm că nu avem camere libere în perioada solicitată. Ne-ar face o deosebită plăcere să vă primim ca oaspeţi într-o altă perioadă. Salutări însorite din St.Johann
Remarks about the translation
I had two bridges for this one, here they are :
Salvo's bridge, thank you :) "We thank you for your request, and we are glad, that you have chosen our house (here: hotel/pension) for your stay. Sadly, we have to inform you that we have no accommodation facilities available at that requested time. It would give us great pleasure to welcome you at a later date as our guests. Sunny greetings from St. Johann"
Lein's bridge, thank you :) "We thank us (must be a typo: should obviously be ‘you’) for your inquiry and we are happy you have chosen our (guest)house for your stay. Unfortunately we must inform you that we don’t have any accomodation available for the date you wish (want). However, we would be very happy to be able to welcome you as a guest another time. Sunny greetings from St.Johann (I think this is a place)."
