Positives: The location of Jacqueline's flat is very convenient to shopping and sightseeing in central Madrid. Her apartment is modern and was spotless, and appeared almost exactly as in the photos, with the exception that there was no rug in the living room as shown online. While the second bathroom was tiny, the main bath was spacious. Linens and towels were fresh and fully adequate. Jacqueline was pleasant and responsive when we needed details to connect to the apartment's wi-fi and had other questions. One of the two air conditioning units, the equipment in the main bedroom, worked great and helped cool the apartment, as the other air conditioning unit did not operate for us. Fortunately, the weather in the evenings was pleasant, and we were able to keep the front window open while we were in the living room. The elevator worked well for us. The apartment was secured with an impressive, simple-to-operate, yet massive locking system on the door. I would recommend visitors arrive during daylight hours, as your first impression will be infinitely better than should you arrive at night, for the reasons noted below.
Negatives: We scheduled well in advance with Jacqueline to check in between 7 and 9 p.m., as we were driving to Madrid following visiting Salamanca. However, the heavy Holy Week holiday traffic contributed to our later arrival, which was a little after 10:00. Jacqueline was not available to meet us, but required we pay the 80 Euro late charge (listed in her house rules for evening check-in and late arrival) to the woman who was apparently hired to be available in the evening show us around the apartment. Initially, our family of four adults spent more than an hour upon arrival debating about our safety in the flat, as we were very put off by the scaffolding over the main, graffiti-painted door to the building, the hundred or so bags of cement lining the right side of the building's inner entry way, the open door to the dark, dusty, courtyard which was under repair and unusable, and the impressive locking mechanism for the entry door to the apartment. Jacqueline told us of the scaffolding shortly before we arrived, but we knew of none of the other issues. The stateliness of the building was not visible. The environment looked much less threatening in the morning, and we focused on enjoying sights in Madrid during the day. Ironically, the scaffolding over the building's main door became a bit of a handy marker for us to find the building when we were ready to return to the flat in the evenings.
