Javier is an excellent host - very responsive to messages and queries. He was kind enough to leave a selection of very useful food and drink items, including bread and milk.
The apartment was very clean and tidy, and as exactly as shown the the photographs. There are easy transport links to all parts of the city - we used the T10 travel tickets which cost E9.95 for 10 trips, including the surface train to the airport.
There are three supermarkets within a few minutes walk of the apartment, and although these are closed on Sundays, there is a small Supermercat shop not very far away, for emergency purchases!
Javier's help and local knowledge enabled us to get to the airport in time to catch our return flight, in spite of the widespread public transport strike. He really is an excellent host!
