I stayed at Helen and Martin's apartment for one month while working in Madrid. The apartment is in a great location just by the Plaza Mayor and the La Latina district. I found the apartment brilliantly fitted out, very comfortable and look forward to staying there again. Martin and Helen were wonderful hosts and I very much enjoyed meeting and going out with them both. Their tips for exploring Madrid were superb and they were more than happy to offer help and assistance if I ever needed it. I look forward to visiting them again and would recommend the apartment in the highest possible terms if you wish to stay in central Madrid. A great all round Air BNB experience!
