No, the place was not in the habana vieja, it's a long ride. You need to choose, going in "la Finca" or Habana Vieja and take a cab just for that, it's more then one hour long from Capitol. Not usual from habana taxi

I'm sorry but I really don't know the hours of operation.

Hola puedes visitarla el domingo solo en la mañana

Yes public restrooms are available but you can’t use Papa Hemingway’s toilet.

I know that for a long time it was closed on Sundays. I thought it still was closed on Sundays, but the website hemingwaycuba (TripAdvisor won't let me post the actual website address) says it is open 10-4 Mon.-Sat. and 9 to 1 Sun. You might try calling the museum at +53 7 8910809 (probably need to speak some Spanish). Also, try emailing one of the good local tour operators in Havana such as Cubaoutings, either from their website. They can respond in English.

Man kommt in das Objekt, kann aber nicht in das Haus, allerdings bekommt man gegen ein kleines Drinkgeld Fotos mit dem eigenen Fotoaparat vom Personal gemacht.

Hi, we just took taxi from el Malecón to museum, they waited and took us back. We paid 5 per person total 25 cuc just for cab.

Hemmingway's house is a must if you are in Cuba. I was not on a cruise nor on a tour- I was visiting family (after 54 years) and had a family friend drive me there.

If you are in Havana, approach one of the drivers of the old cars and barter. Pick a good one. Most of them are great guides

Yes his boat is housed there. It was great to see. Also it is located by the pool area where you'll see a lot of photos of him. The house you can view from the outside, but you can't walk through because the want to preserve it the way it was left originally. But you are allowed to take photos from the outside, and if desire you can ask the attendant that stands inside the home to take photos with your camera for you. Of course it would be nice to give them a tip.
