We loved the apartment - clean and fresh, with great views. It is certainly well positioned, with easy access to transport, restaurants and some of BA's special parks.
We especially enjoyed Marcelo's informative - and very entertaining - introduction to the apartment's facilities and the whys and wherefores of the city!
One minor hiccup - we had arranged for a late checkout, but early afternoon received a call that the apartment was needed for a last-minute booking and we had to vacate. That spoiled our last few hours in town a little bit and we suggest that a more appropriate system is put in place.
But that aside, we would highly recommend Ralf's place.
