In the contexts of real estate and lodging, amenities are any tangible or intangible benefits of a property, especially those which increase the attractiveness or value of the property or which contribute to its comfort or convenience.
Tangible amenities might include parks, swimming pools, health club facilities, party rooms, bike paths, community centers, doormen, or garages, for example. Intangible benefits might include a "pleasant view" or aspect, low crime rates, or a "sun-lit living room", which all add to the living comforts of the property.
