We spent 10 days in Marianas Apt. The location is excellent, close to Trinidad Metrostation with a direct line to the airport, right in the middle of the old town. Closeby are cute little shops and plenty of bars and restaurants. Which is a good thing since you need to go out for eating. The kitchen is very small, no space to put your groceries anywhere, let alone cook. The apartment was very clean and has been tastefully redecorated, in a very functional way. Overall it was a good experience but we found the price of 90€/night (incl. all fees) a bit steep.
