I stayed for a working week in Barcelona and enjoyed the fully equipped apartment in central Barcelona.
There are several supermarkets and public transportation near-by. Also, there is a cafe super close where you can get your morning coffee :-) During nights I had to close the windows as the street is always crowded.
The checkin was very convenient and the apartment was comfortable for one person or two.
One thing I didn't know and didn't expect was that you have a key to turn the power on and the power gets off when you leave. As I was there for working I had to charge several devices and it wasn't convenient at all that I couldn't charge them when I was out :/ Felt like a hotel and not like a home in that regard.
