Melvin wasn't around, but Ivy his manager was extremely helpful with information about buses, maps, metro etc. Welcome Wine and beer most appreciated!. Although the apartment is very small, and the bedrooms challenging due to slope of the roof, the kitchen/dining/lounge space is fine for the 4 of us who stayed. We were out and about, so didn't need internal space- when in Madrid, you don't stay indoors in your apt!!!
Location very central- close to shops, restaurants, bars and sights- 50m from Hop-on/off bus stop!
