A very simple accommodation but with everything that you may need: a local bus and a metro line near by, within 2-5 minutes walk, huge market that works all night (but note, no selling alcohol after 10 pm in Spain!), shops and restaurants near the bus station...
Paloma is a very caring host who tries to help in every way and if you don't like dogs there is really no reason to be worried: her dog is excited only the first time he meats you but after is perfectly calm and unconcerned about you!
