Try this:

 var response = proxy.GetInformation(
        new TravelAgencyService.Messages.TravelAgencyRequest()
        {
            Accommodation = comboBox1.SelectedItem.ToString()
        });
    List<string> kindOfAccommodation = response.Offers
    .Where(offer => offer.AttributeOfOffer == valueToFilter)
    .Select(o => o.RodzajZakwaterowania )        
    .Distinct()       
    .OrderBy(c => c)
        .ToList();
