VERY GOOD ! I enjoyed my stay and it was good relaxing place to rest in very intensive schedule that I had in Madrid. Good value.
It's nice separate unit with private entrance, 4th floor (with elevator). In the center of the center ... but - very quite small, one way street that has very minimal use. Very safe feeling to walk in/out.
Many places to visit in Madrid are within few minutes of walk.
Inside - everything is as describes and shown. No surprises. The room is big, bathroom renovated some time ago and looks good. The kitchen is small, equipped, good for something as breakfast or light meal. Nearby is good Lidi supermarket (till 23:00) but you don't really need much - so many places to eat/drink in Madrid... for all tastes and budget).
Kristian is very friendly. Before arriving, he suggest the best quick/cheap way to arrive, supplied all the info how to get in , doors codes and so. (I arrived late at night and he was away). He responded quickly to every question or remarks I made, and was always accessible in whatsup.
Nearby Metro are Tirso de Molina (one block, takes you to bus stations if you plan one day tours outside Madrid ot return late an night) and Sol (400 meters). Nearby is pleasant plaza Santa Ana. I came late at night and walked around for an hour, with my luggage... before going to the flat....
Surely a place that i'll come back to.
