We were met by Xuan outside his home just a short walk from La Latina metro station (easily accessed from the airport). He is a friendly and engaging guy who speaks good English. He gave us a quick tour and after a pleasant chat left us with keys and some recommendations for local restaurants to enjoy.
Xuan's apartment could not be better placed for all the delights of La Latina.
The best road of Tapas bars in Madrid is only a couple of minutes away (Calle de la Cava Baja) and one of the nicest Tapas we eat and drunk in was literally round the corner (Txirimiri).
Plaza Major, Mercado de San Miguel and a lot of the best of Madrid is all a short walk away.
However Xuan's apartment is in a very quiet road and faces into the central courtyard, so is blissfully quiet if rather dark (unless you turn the lights on of course!).
The apartment itself is both spacious and quirky with very few doors internally but you do get a modicum of privacy with curtains . . . and there is a door on the toilet.
The beds are very comfortable and the shower is both hot and plentiful.
Do note that smoking is allowed in the apartment (as described) and therefore has that unmistakable aroma. But if that is not an issue then you'll struggle to find a place better suited to enjoying the delights of Madrid.
