I randomly decided to travel after my layoff and will be in Paris for 3 nights tomorrow. I'm in desperate need of hotel recommendations as I have no clue where to stay. I'd greatly appreciate any suggestions and here's what I'm looking for.

Budget: $200-350 per night (obviously the cheaper the better)

Arrival: Arrive Monday around 23:00 on a Eurostar from London and depart Thursday morning on a train to Spain.

Vibe: Very open and would like to do more exploring and just see the sites one time. Looking for a safe area that is accessible to the metro.

Things to do: Open to any suggestions.

Thanks a lot in advance and I'm realizing now it wasn't the smartest idea to pick up my luggage and go on a cross Europe tour on a whim.
