Eduardo was very nice and helpful. He responded very quickly whenever I had any questions. The flat is also very nice. It is small ( like many things in Madrid ), but my girlfriend and I have no issues. You might hear people talking or walking outside the common area or streets, but it was minimal and didn’t bother us. The location is amazing!. It has many little mom and pop shops nearby and lots of cafes and places to grab a quick bite. Many things within walking distance such as Gran Via, Puerta Del Sol, Mercado San Miguel, and Plaza Mayor - none of which is more than 30 minutes. However, if you hate walking, Tribunal and Noviciado metro station is very close and easy to use. We did more walking to be able to take more of Madrid’s culture in, but ended up using the metro a few time because of how cold it got during late nights.
Use the hairdryer that they offer - mine shut down the apartment’s switch, which was an easy fix, but kinda annoying.
Bonus tip: the International Market on Calle Del Espírito Santu is very convenient if you need some quick supplies or food. The people that work there are very nice too.
