We stayed 5 days in the apartment. It was quite convenient. The apartment looks like on pictures only at the pictures all rooms, kitchen and bathroom look bigger then then they really are. There was a coffee maker in the apartment but it didn't work, luckily we had our own.
The location was quite well. But there were not many restaurants in the neighborhood, so that we had to travel to the city center, and, because the location was quite far from the tourist area, it was difficult to communicate in any language other than Spanish. The metro station was not that close – it is something to consider when travelling with kids.
However, I would seriously consider staying in this apartment or any other apartment hosted by Mad About You, as the host is insincere and doesn’t care about his guests. Our experience was that at the beginning the communication went well, check-in was also good, but as the host didn't want to deliver what he promised before apartment reservation, he stopped responding to any form of communication (calls and messages). He constantly lied about things to deliver until the very last day and even after departure. Additionally at the check-out the host lied about time we had to leave the apartment. We discovered this because we were waiting for him at the apartment for 2 hours after check-out time in order to be able to communicate with him. It was really disappointing. The host has promised me an invoice and has failed to deliver. Due to business character of my travel, the invoice was critical criterion of my decision.
