We are a couple with a 9 year old son, traveling from Montreal, Canada, first time users of Airbnb and we stayed at Ester's apartment for 5 nights. From the very first moment we saw the listing and started inquiring about it, communication was absolutely outstanding: we flooded Ester with questions and every reply came fast and precise.
When we landed in Barcelona we called the number we were provided; we were promptly answered and told to head towards the apartment, somebody will be waiting. At the apartment was already Catherine C. from Stay Unique (the company that manages the apartment): a/c on, shades pulled, the flat chilled. Extremely professional, she gave us the keys, instructions, phone numbers, maps, even advice where to dine and what to see.
The apartment is exactly as described: cozy, very functional, spacious, well lit; the kitchen is fully equipped, coffee machine, espresso machine, toaster, water boiler, utensils and the list can go on. Bathroom is large and super clean. WIFI worked perfectly the whole time. Two minor issues (a clogged shower and a window that wasn't opening very well) were solved a few hours after being reported.
I left, however, the best for last; after stellar communication and functionality, comes its best asset: LOCATION. When you exit the building, a few steps to the right you have a grocery store glued to vegetable/fruits one while a few steps to the left bring you to the metro stop (and from there the whole city is yours). Is also less than 15 minutes walking (with a kid!) distance from Plaza Espana and its Magic Fountains; the walk is through a safe neighborhood full of shops and very nice restaurants with terraces.
To make a long story short: I can't recommend this apartment strongly enough for a family who plans a stay in Barcelona to discover its beauty. Thank you Ester for everything!
