Alejandro's place is clean, cosy and offers everything you need for a short stay with family or friends. He was a wonderful host, very thoughtful, providing us with umbrellas for the rainy days ahead. The place looks like in the pictures, in addition you have two picturesque balconies.
The location is perfect, I highly recommend you to explore the beautiful streets around the house by foot, you will find the best street art! Check out the little designer shops, cafés for breakfast and tapas-bars in the evening. Fantastic churros-place right around the corner for midnight snacks after partying :) Be prepared for the noise in the night though, the street never sleeps and neither do your neighbours. All the sightseeing spots are easy to reach by metro (the nearest station Diagonal is a 5-7 minutes walk away).
The neighbourhood Gràcia has so much to offer if you want to experience the city in a non-touristic way. Enjoy!
