We had a wonderful stay in one of the Barcelona Studios. It's very close to the Miami South Beach and you can easily access it via bus, also directly connected to the airport.
Our Apartment was very well equipped, also with little details. The kitchen has everything you need for preparing your own food. The only downside was the fridge, which was little bit noisy.
The AC worked fine and there is also an additional fan.
We got a lot of towels and also extra beach towels, which was a nice extra. In the lobby you can also find free stuff from other former guests. In the lobby and around the house there were some cats.
Adriana, the owner, was very friendly and always available for questions. It was also possible to store our luggage before checking in.
In general it was very quiet and the wifi worked fine.
