I stayed one week in Carmen's house, and it was the best part of Madrid trip. The house itself is very well located, near to atocha train station n metro, walking distance to most of the museums and tourist attractions as well. Room is basic and clean, and there r 2 bathrooms so I never had to wait for shower or toilet. But for me, the best part of this place is people, Carmen and her sons (also the cat!) r extremely friendly and helpful, also the other tenants I met there were also very nice too, we had some good times together. I didn't feel like a guest there, it's more like living with friends and family, it's truly a home away from home for me. Thank you Carmen, Nacho n Uje for your great hospitality, and I wish I can go back to this lovely place and see you again one day :)
