From the early beginning till the end of our stay, everything was perfect. Cristina provided us with detailed information prior arrival. When we arrived, she explained everything we asked about, and gave us several ideas about places to see in the neighborhood. We tried them all, and loved it re part of their family. I really recommend staying with them. Nice & friendly, easygoing people. The location itself is great. You can reach the city center in 15 min by train, or in ~40 min (?) by bus ( directly from the Trafalgar square).
