My daughter and I had a wonderful two week stay, during which we were working remotely for part of the day while doing tourist things with the rest of the day. The apartment was perfect for our needs -- grocery store and metro stops close by (Santo Domingo and Plaza de España) and good wifi, plus an easy walk to many things including the Palacio Real, Sol, etc. The apartment was great, and check-in and check-out went well.
We had just one issue with communication that I wanted to note for this review. On our first day, we had two separate workers come by to fix two different things in the apartment. They did not have identification and we were not told in advance that they would be coming; they had keys to the apartment. I texted the managers (Minty Stay) asking that we be told in advance if anyone else needed to come into the apartment, but never received a response.
