...what large city (besides London, Paris, & Rome) could you base yourself in for an entire week?

Most likely I'd stay in Vienna. Why, do you have a free hotel stay?

Madrid

Sorrento

Barcelona for sure

Florence, Milan or Venice

London. It is far more expensive for rooms than either Paris or Rome.

In fact, my wife & I made that choice - I have 6 free nights booked at the London Park Lane in June - from Hilton Honors points. Combined with free air tickets from Air Canada & we are travelling cheap!

We have also been to Paris & Rome recently so it made sense.

For the 4th try!

Budapest

Of course, it would be St. Petersburg, Russia.

Berlin, Vienna, Amsterdam. This last one has easy day trips to The Hague, Delft, Haarlem and other intersting locations.

It's always hard to fine great, inexpensive places to stay in Amsterdam and London, so one of those.

This is a europe board but the answer would have to be Tokyo for a free hotel stay.

Hotels in Britain seem disproportionately expensive compared to other countries, so if London is out, I'd pick Edinburgh, especially around the festival.

Otherwise, Amsterdam or (I hate to say it) Geneva. Or Barcelona. Or Copenhagen. No, wait...

Vienna, Prague, Dublin or Edinburgh.

Lisbon for sure! I stayed there last June for a week and still didn't get to see all of it. Very homey, great food, good prices, great fado music, friendly people, fabulous weather, lots of easy day trips (Sintra, Cascais, Obidos, Serra da Arrabida, Troia.) I can't wait to go back.

Tokyo-so I could visit my son.
London-it is so expensive.
Paris-cuz I wanna go back to Paris!
Florence-I missed it a couple of years ago.
Venice-before it sinks.

Since I can't have London, Paris or Rome...

Venice
Aux en Provence

I also would choose Munich, Venice,Barcelona, or Taormina!

Somewhere on the Amalfi Coast.
