We visited the Spoedtest behind the Victoria Hotel right across from the Grand Station. Like many other reviewers, we did not have a pleasant experience. The nurses/attendants were incredibly rude and unhelpful. It was pouring rain out, and they refused to let us stand inside to even ask a question. Their online system didn't work with Chrome and kept giving us an error message. One of our two appointments were randomly canceled without explanation, requiring us to stand in the rain again to re-book another test. (BTW, Safari is the only browser their system works on.) The attendants were zero help and didn't inform us we needed our passports until after we paid so we had to take the train back to the hotel to retrieve them (a valid license doesn't work, even though their website says it does) and return in the rain yet again. Once there, the technician shoved the swab so high up I had a bloody nose after. There's no reason for that to get an accurate test. Deeper does not necessarily mean better! All in all, it was a completely unpleasant experience and I'd recommend finding another source for your mandatory Covid test to return to the USA.
