Okay, the Courtyard Marriott in Belgrade is THE place to stay. It's in the heart of the city, and the staff are super friendly and knowledgeable. But the small part that I love so much, is the water refilling stations on EVERY floor. I know it seems so minor, but I love a hotel that is considerate of their guests, instead of trying to overcharge them. They provide you with a water pitcher in your room and the water stations provide hot or cold water. They have hand sanitizing stations on every floor. The place is immaculate and the bathrooms are spacious. The hotel is quiet, even though it is in the HEART of the city. It's so convenient because you can walk to so many incredible tourist attractions, restaurants, museums, theaters, bakeries, coffee shops, etc. I've stayed here twice in the past 8 months and I'll stay here every time I visit the city.
