Stayed at Albert’s for 2 nights and it was perfect! The location is great two blocks away from the Sagrada Familia and a metro station right there! Lots of places to eat and drink all with in walking distance.
The flat was a good size and had everything you needed. It was decorated to a very lovely standard!
Albert and his team were great, quick responses, easy check in and check out and also have somewhere to store luggage if you need too.
If your looking for places to visit/things to do I would recommend:
The cable cart that takes you over the city (beautiful views)
Hop on hop of buses (good to see all the sights)
Free walking tours (takes you to places you may not visit)
Arc De Triomf, Citadel Park, Park Güell and La Rambla.
Many other places too :)
Also check out the rickshaws that are around the city really good fun!
