Nice residential area near the Monumental metro station. Check in was a breeze, and we were given a lot of information about the local area. The apartment was well equipped with everything needed for an extended stay. My wife and I stayed for just over a week, and really enjoyed being here.
The only thing to keep in mind when booking is the size of the second bath/shower. This is one of the smallest showers we've seen, and can be challenging to use. The room works great as a half-bath. The other bath is a good size, and we ended up sharing it for showering purposes.
On the weekends you can see the top of Sagrada Familia lit up while laying bed. My wife really liked that feature. Overall, we highly recommend this place, and especially the host (if they have other properties). They are very nice people, and try to ensure you have a good stay.
