Hi
We purchased furniture packs for two apartments from IR - I would say just make sure you either get everything in writing from them or put everything in writing for them to acknowledge - the packs were the best we could find - they were always helpful - but - they got a lot of things wrong !!!!
Just make sure you put EVERYTHING down in black & white so when things do go wrong you can refer them back to what was originally requested/ordered and then as I say they are actually the best we could find. Spain being what Spain is !!!
