We had a great stay in this apartment. The apartment was clean and tidy, with very high ceilings which gives a great feel of space.
It's very well located, 2min walk to the metro, with restaurants and shops nearby (even a small shop that works 24/7), although if you want to eat out close to the apartment on a Saturday night I'd recommend making a reservation, as we sadly found out :)
Fernando and Piia are very nice and received us quite well (and speak English perfectly in case that matters). It's a great apartment, although with a small bathroom/toilet and steep stairs in the building, so I wouldn't recommend to anyone with mobility problems, but except for that you should have a great stay.
