We were fortunate enough to stay at Jose Maria's place from June 25th to June 29th. When it comes to Airbnbs, I think you have to look at 1) the accommodations 2) location and 3) responsive of the host.
When it comes to accommodations, it is perfect for either couples or families with 1 or 2 children. My wife and I travelled with my teenage daughter (16 yrs) and it was perfect for us. It had everything we needed, was very clean and well maintained. The two person terrace is perfect to have an evening drink and people watch. And thought it was cool how the elevator opened up right into the suite.
When it comes to location, not sure you can find a better location than the Born. Located adjacent to the Santa Maria Basilica, you leave the building and restaurants, stores, supermarkets, and even a Starbucks are all stone throws. It is a lively area, so be prepared for a lot of activity well into the early hours of the morning. Many high-rated restaurants are close by, including the home of the best croissants in Barcelona (Hofmanns), and the beach and the Ramblas are all within 10-15 min walks.
When it comes to the hospitality, Jose Maria and Belkis were first class. Always in communication with us prior to our reservation, and Belkis met us during check in and explained everything. She also provided daily tips and advice on getting the most out of the city, and also helped us secure a taxi on the way back to the airport.
For sure if/when we return to Barcelona, we won't hesitate to try and stay with Jose Maria again.
Muchas Gracias!!
