The apartment is a really good place to stay if you are in the Barcelona for a few days. The location was amazing, you step out into the heart of Barcelona and are surrounded by all amenities.
Communication with the host was excellent, as was check-in.
A few issues of note:
WIFI issues throughout the time we spent, very slow connection at times.
Electricity was also an issue as it cut out many times during our stay. Power cuts happened a few times a day, when using the heating.
The water when showering would also go cold after a few showers and this was an issue for a 7 people sleeping apartment.
