Alex was great, even before I arrived in Barcelona. He gave me great tips, guided me to purchase tickets for the places I wanted to visit in advance and told me about a hidden gem in Barcelona. The place is exactly as described and there is nothing missing from it. The location of the flat is perfect. Barcelona is very easy city to navigate, for the most part. Alex left a map for me and also added a sheet of nearby grocery stores, bakeries and restaurants. Although he was away at business, his wife welcomed me in the flat and everything was ready all the same. Thank you both for everything.
(I locked myself out of the flat once and was able to get a hold of Alex fairly quickly...even though he was out of the country)
