This place is in a great, central location, steps from La Rambla and close to Barceloneta as well; do note that El Raval can get seedy after dark, so be wary. The apartment itself is set up to give the guest maximum privacy - the guest room is on the opposite side of the fllor. The building lobby will not win you over, it's very dated but it belies how nice the actual apartment is. The apartment is also on the third floor which is difficult if you're carrying many bags.
I met Gan at her office - a quick trip from her apartment - since I arrived on a weekday. She was very attentive and responded to emails very quickly and provided excellent directions. Great stay overall.
