Spanish word for you are welcome?

"Welcome" can have two different meanings in Spanish. In English we use this Word to denote recognition of a favor (Thanks - You are welcome). We also use it to greet someone to a location (welcome to my house).

In the first case, most of the time the response is "de nada" or "por nada", meaning "it is nothing". The term "so welcome" would be difficult to translate in this context.

The second meaning could be "eres tanto bienvenido, señorita".
