We stayed at Carmen's for 12 days. It was a long time but she still made sure we were super comfortable...it felt like being home. She lives in a quiet residential neighborhood - it has everything (cafe & bars, grocery/market - 2 blocks away, and a library (15 min away) that is like new and has books in many different languages). Carmen is really friendly and conversational. She only speaks Spanish but is somehow able to overcome that with gestures, expression, and google translate. Her place looks exactly like the pictures and she is super clean. While we were there she even washed our sheets, cleaned our room, and allowed us to do a load of laundry. The city center (Sol) is about 45 minutes by Bus #6 and the bus stop is about a three minute walk from her house. Wifi is very fast. The only problem we had was about the smell of cigarette smoke in the house but aside from that everything else was perfect.
Thank you Carmen for welcoming us into your home and being our family while we were in Madrid!
