I couldn't have picked a better place to stay. Angel communicated with me regularly before I arrived and met my daughter and me at the door. He showed us how to turn on the air conditioning and raise and lower the blinds and provided a document with information about the dos and don'ts of his apartment. Later, he sent us a list of places to eat.
The apartment is on a quiet street without traffic, a half block from a busy thoroughfare that leads to the Plaza Mayor. I thought it was a great location. It was a 20-minute walk to the Prado and Reina Sofia museums, although it's good to have a SIM card to access Internet because the streets don't follow straight lines. It's only two blocks to the La Latina metro stop.
In Angel's place, the Internet connection was good, there was plenty of hot water in the shower and the air conditioning cooled us off.
Angel told us of a place several blocks away where we could store our bags for several hours before going to the airport. It's all electronic, i.e., you do it without seeing an attendant.
Angel is a super host! I couldn't recommend his place more highly!
