I stayed at Oliver's place for weekend after a business trip for a solo adventure experience. Best decision I made. Oliver was the kindest host. We were in contact prior to my arrival, he greeted me upon arrival, helped with reservations and suggested the popular places to visit. His apartment was very clean and my room was private with my own private bathroom. The apartment is in walking distance to all the major historic site seeing places. His pictures online do not do the apartment justice. Its so much better than what I expected. Very cozy. Oliver made my visit to Madrid so much better than expected and I am very thankful to him for that. I will definitely be staying with him on my next trip and have already suggested his place to many friends! This is a MUST BOOKING!
