Mercedes's place was amazing!
To start with, the location couldn't have been better - only a few minutes on foot to the main monuments in the city centre and a few metres away from the Maestranza Theatre (if you enjoy classical music, opera etc, 100% recommend it!), also the bullfighting ring, which you should visit even if you don't like bullfighting, it's a beautiful monument!
It's also very close to loads of bars and restaurants. I love the neighbourhood and Mercedes was great at giving us tips on what to do and where to go.
She was also very easy to communicate with and very prompt to respond. Would recommend in a heartbeat!
