First of all: THANK YOU to each of you for your kindness in feedback :-)

I submitted my payment request to the owner of the flat in Schoneberg & am awaiting approval. Once I get the address, I'll let you know. Then we can determine the closest point of arrival.

The owner has been quite responsive too, so I am sure he'll be a good guide.

Here is the link to the place I decided upon to rent for the 4 days:

Now, I am of course thinking if 4 full days in Berlin is enough to see the top historical places while also just having some good old fashioned downtime in the cafes, and other neighborhood watering holes.

Also, I was even maybe thinking of getting to London to visit a family friend of mine after the 4 days. Easy Jet perhaps? Train? hmmmmm.

Hugs to you all for your guidance again.

Patrick ;-)
