Hey,
your feelings are completely natural, esp as you got on so well with your last therapist and are probably still grieving the loss of that relationship in a way, so a part of you was really hoping that therapy with the new therapist would be the same and this includes things like the office and waiting room. I think you may compare your new therapist to your old one for a while until you adjust to the new way of working. I think if by 5 or 6 sessions you really don't feel things will become comfortable at all then perhaps it would be best to try someone else.
It's good that you highlighted some positives already about your new therapy situation.
It took a lot of strength to go to someone new so you should definately be proud of yourself for that
