Finding apartments/interconnecting rooms, France/Germany towns?

[NotCitrus]

I'm trying to find suitable places for us - we have small children but want a separate bedroom from them, so need either interconnecting rooms or an apartment. Either self-catering or buffet breakfast basis.

And want to be in a city or decent town to do sightseeing and wandering about somewhere that clearly isn't England - so either somewhere reachable via Eurostar, say three hours beyond Paris/Brussels, or short flight from Gatwick/Luton. Germany would be my preference but France may be easier.

Are there chains of apartments to rent in those countries, or hotels similar to Premier Inn that do interconnecting rooms? Any recommendations gratefully received.

bump?

We stayed in a hotel with interconnecting rooms in Germany - part of the Melia group. Hope this helps. We did searches for family rooms.

www.booking.com allow you to search for apartments, a quick look shows a few options in Berlin so presumably in other places too.

Thank you goshh - my searches for family rooms just come up with the extra beds in one room, which is explicitly what we don't want (no-one gets any sleep, so better to have fewer nights in multiple rooms).

Will have a look oldboots.

I spent all my holidays in Germany as a child they have family rooms as standard fixed price.... That was the 70's??

Look at airbnb, holidaylettings, homeaway etc. for apartments.

We've stayed in NH hotels in Germany with interconnecting rooms. And holiday inns in Switzerland. It's never normally an issue. And both have buffet breakfast. Where have you looked?

Citadines do aparthotels with multiple rooms. Lots in France, but a few in Germany. I would think self catering would work out loads cheaper, using one of the companies mentioned by butterflies, or Owners Direct.

Loads of recommendations for Airbnb from friends and family.

Thanks Butterflies. Booking.com doesn't let you filter by interconnecting rooms, andI thought connectingrooms.com would solve my problem but it has few hotels and when it does list them it refers to "family rooms" and you still have to contact the individual hotel to find whether that's connecting rooms or just one large room...
Will try Citadines and NH. I don't want to stay in someone's house (stopping the 2yo from smashing stuff would not be a holiday !) but Portofino is probably right self-catering would be cheaper than a hotel, even if we do love hotel buffets.

Pierre et Vacances maybe another option.
