We are a family of four(two adults and two adolescents). We had a marvelous time in Markuss' apartement. The apartement is spacey, with beautiful artworks, and very aesthetic and pleasant. The kitchen is well equipped, and we cooked there daily. Markus and Irina were very helpful, accesible and pleasant from the very beggining. We landed in SF early in the morning and Irina met us in the apartement and enabled us to leave the luggage, although the flat was still inhibited , and later on she brought our luggage up to the flat and we could tour the city freely. The neighbourhood was pleasant and there were some good mexican restaurants and a supermarket and cafe's close to it. It's very close to castro. we realy recommend staying in this apartement!
