I have just returned from staying 2 nights at the Muralto. I stayed with a friend and we had a twin room. The apartments are a 2 minute (if that) walk from Arguelles Metro station, which in turn is situated right next to a well equipped supermarket. From the airport it is 2 different lines on the Metro, which is easy enough to work out routes for. We got a 3 day ticket for I think 13€. The apartment had a bedroom, living/dining room, bathroom and very small kitchen. There was a 2 ring hob, microwave and fridge, which was fine for us as we were mainly eating out anyway. We did manage to cook spaghetti bolognese on our first night though! We called down to reception and asked for pots and pans which they sent up straight away. The only problem was they could not provide a kettle or toaster. We boiled water in a saucepan instead and made do with just bread. Free Wifi was a great bonus. Ask at reception for the code. All reception staff are very friendly and (unlike most people in Madrid) speak very good English. We were surprised that a lot of people do not speak English at all, but that just encourages you to brush up on your Spanish!
Things to do in Madrid:
-Temple of Debod (10 min walk) an old Egyptian temple with stunning views over the city.
-Zoo/Aquarium - best zoo I have ever been to with pandas, dolphins, sea lions, koala bears and many more amazing animals. Catch the Metro to Casa De Campo then either walk 15 mins or get the bus to the park.
-Parco Retiro - an afterthought for us but it is not as far as it looks on the map and has so much to look at including an amazing boating lake. The Metro takes you right into the park
-The Palace - was closed during our trip which was very disapppointing but it is amazing to look at anyway.
