I can't say enough positive things about Mike's place or my communication with him. Prior to arriving through check-out, Mike was either a step ahead of me or quick to respond to any questions I had. His property manager, Angela, is also wonderful and incredibly kind. As for the apartment, it's one of the most well designed units I've seen for the amount of space available. My stay was 14 days and it had everything I could have needed, from cooking and laundry to a comfy little office space.
The thing I found my enjoyable is how lively the street is when you walk out of the building. It's always bustling with people, and has numerous restaurants, bars and shops within a couple blocks. If you decide to leave the neighborhood, it's extremely easy access to various metro lines, taxis, or walking to major tourist attractions in Barcelona. If you rent a bike (a few places to rent them within two blocks of the unit - check out Lemon Bikes), the beach is only a 10 minute ride away!
If you're considering a trip to Barcelona, I can't imagine a better place to stay!
