Hi Camille! Thanks for the comments. Some of them help us to getting better. It´s the first time someone have problems to arrive, just because you had the exact address and with (Hidden by Airbnb) Maps it´s no possible to get lost (I was at home waiting for you, so you didn´t had to wait for anyone. I´m pretty sure I told you about my friend before, and I couldn´t introduce him to you because he arrived at 23.30pm from other city and you were resting and I had to go to Segovia (my family´s city). By the way, It´s our home and if I let anyone here, it´s someone that we know we can trust and he or she won´t disturb you in any way. In this case, he was just for sleeping and having a shower in the morning. About the noises... your room is the most quiet of the house (the window goes to a "patio" not the street) and the walls are normal... About the 20 minutes for getting the center, It´s something relative, because you have 20 minutes to Gran Vía, but Chueca is considered center too and It´s 15 minutes from home, both in DIRECT line!. Maybe you can consider to pay more if you need some special qualities next time... Anyway, I hope you have spend a good time in Madrid. Cheers!!
