Bo's apartment is perfect for a big group, it is spacious enough, but everyone can have enough privacy while enjoying common space and the roof top (recommended at sunset!).
The location is very convenient, central and in a lively neighborhood.
Bo is a great host, very kind, attentive and reactive. Communication was super easy. He was very accomodating with our different arrival/departures schedules and we enjoyed spending some time talking with him about his life in Madrid. Highly recommended!
