This apartment is in a great central location for exploring Barcelona, however it does have a few issues to be aware of. The neighbours have left notices on the doors and made complaints on two of the three nights we were here. The host had messaged me when I booked asking us to not make noise after 10pm which I made sure my group was aware of. We never played music after this time but had the host message and call at night asking us to turn off our music. We had only ever been talking quietly in the communal area at the back and so our assumption is that this is adjacent to the neighbours bedroom and on the final night we used the front bedroom instead and received no complaints. Possibly the apartment would benefit from these two rooms being swapped around.
The feeling of constantly being worried about annoying the neighbours did dampen the mood for the last couple of nights.
This is a shame as it is a nice apartment with a lovely terrace and comfortable beds, although a little in need of TLC in the bathrooms and kitchen, with the amenities not being that accurate, note "coffee maker" is a kettle.
