We had a very nice stay at Natasha's place. The flat's location is perfect, about 2 min. walk from the metro station and about 20 minutes walk to Sagrada Familia. It is also easily reachable from the airport both Terminal 1 and 2. The place was clean, the bed comfortable and we had plenty of space to store our things. We hardly noticed Natasha's curious cat, though it did sneak into our room a couple of times. Natasha was also flexible with a check-in time, as my flight got delayed. She also kindly allowed me to pick up my bag after the check out time, so that I can still do a little bit of sightseeing on the day of leaving. Overall we had a very pleasant stay and would recommend it if you are looking for a good value of money and location.
p.s there is a very good cafe around the corner where you can have your breakfast, as well as a little supermarket, and two groceries shops to buy fruits and veg. You can even buy postal stamps in the local tobacco shop and conveniently send you postcards via postbox without searching for a post office. Thank you Natasha for our stay and your tips :)
