Enrique' apartment is situated in a very lovely central location with access to all forms of public transport. The flat has a lot of natural light and is compact but spacious. A lovely friend of his welcomed us into the flat.
My boyfriend and I did have a few issues with neighbours and members of staff entering our apartment unannounced and a little miscommunication. Enrique did respond to our email and apologised for any inconvenience.
I don't know if we would stay there again (it felt more serviced apartment than a home from home..but that's a matter of personal taste), but we did have a wonderful time in Barcelona.
