Pepe provide a warm welcome and showed us around this very nice flat in a great location in Barcelona. Although it is not next to Casa Battlo', and it is not the top floor, it is very close to many attractions either by foot or metro. Just make sure you don't mention Casa Battlo' to your taxi driver or that is where you will end up.
The flat was nicely furnished with a large living area and good kitchen. Bedrooms had a lot of storage space. The master bath was great and the second bath was a little small, but certainly adequate.
The location was quiet and quite secure, especially considering how busy the surrounding area is at most hours. We will recommend it to our friends.
