The stay was very good, and the aparment had everything we needed. We liked the interior and decor which was very tasteful and nice. We would recommned this place and would come back next time. The apartment is located near Atocha station where you can take a bus to/from teh Airport. The metro station is also 2 minutes walk. I would highly recommned this place.
Be prepared to pay 10eur if you are checking-in late. We arrived at 8pm and had to pay 10Eur in cash to the person who let us in. I understand this was mentioned in the house rules that check-ins from 8pm onwards will be charged extra. However, we think this is a strict rule as we kept updating the host of our arrival time and arrived at 8pm. Also the person didn't give us any receipt of accepting cash money (he spoke basic English and used Google translator), therefore he called the host lady - we asked her for a receipt and she said they will see what they can do about it. Later we decided not to bother, but this was an unpleasant surprise. We will read the rules more carefully next time.
