First of all, you will love Madrid; it is a fantastic city. And now Romulo's place: The location is fantastic!! it is walking distance to many attractions like the Royal Palace, Mercado San Miguel, Plaza Mayor... and if you don't mind walking, you can even walk to the Museo Nacional de Prado. Everything is walking distance to the apartment. Also there are tons of bars, restaurants in 2min. walking distance and also along the way to the main attractions. The place is great for two people - very spacious. Romulo is great with responding to the messages if you need to reach him. We have not feel unsafe anywhere in Madrid yet alone where the apartment is. It is very very safe!!! Just remember that the apartment is on the lower level so there is a direct access to the street from the side sliding door - which we used it all the time. Because of it's level, beside the main door, there is not much day light, so you might need to leave the curtain open ( No privacy though), or just leave the lights on all the time. There is no water or anything in the fridge so for the first moments, buy water, wine etc before getting to the apartment. Supermarket hours are very different than US so otherwise you might need to walk to the main street to look for an open market - you don't want that as soon as you arrive. Also there was an odor coming from the toilet during our stay, we guessed that it is because the apartment is located on the below ground level so maybe that is the issue and there is no really an air flow since there are no windows that you can open - just the door...
