I had a very pleasant stay in Teresa's home. The flat is clean, comfortable, well furnished and warm (I was there in November when it's not so warm in the street). The same goes for the bedroom. The double bed is well presented and comfortable with soft bedclothes. There is a lot of wardrobe space, if you need to hang up your clothes and a large desk space. The room is warmly lit by one or two bedside lamps. I slept well, I heard one or two voices in the street but nothing that disturbed me.
Teresa and her family were very welcoming and made me feel at home. I was travelling alone, so it was nice to chat to them for a while in the evening. They were very attentive and did their best to find out about the public transport connections I needed to make. Teresa provided a map of the city and gave me some good recommendations for places to eat.
My stay was great value for money, and I will try to stay here again the next time I come to Madrid.
