This was a very nice accommodation in a very central location. We never even had to board the metro until we left town on the last day. Aside from that, we walked everywhere we wanted to go in 35 minutes or less, which was a great way to see the town. Though, it was quite cold while we were there, the apartment stayed warm and it had all the amenities you could want- soaps, detergents, washer, heated drying rack, TV, cleaning supplies, hair dryer.
The place is very dark in the day time, as it's on a lower level and the only windows face into the courtyard, so no natural light shines through. We didn't mind too much, because we were always out during the day.
The only thing that wasn't great was the noise level. There's a strong echo when people walk through the courtyard and up the stairs. Earplugs help a lot if you're a light sleeper.
We were happy with our experience and would definitely recommend this place.
