I stayed with a work colleague for 3 weeks in San Cristobal. The apartment is very well equipped and stylish, and has great transport links for both the Metro and San Cristobal train station. Despite having some reservations about the area initially, we encountered no trouble at all, the locals seemed friendly (though I don't really speak Spanish) and it was very quiet at night which is big plus for me being on business there. The only negative I'd say is that parking can be a challenge but you can always find something, it just may not be outside the apartment block. As a base it is great, you can stay local or head to Getafe / Madrid using the public transport if you wish and most of all, Liliana did a great job of making us feel welcome and showing us around the flat - all calls and messages were answered promptly and there were no issues with the language barrier, so a big thanks to her and all at MadreamsRent, I'd definitely use them again.
