We had a great stay in Mercedes appartement. It is perfectly located in an authentic house from plaza real of the Gothic district in Barcelona. The apartment is very charming and the terrasse has an amazing view.
Mercedes was a great host, very kind, has given us tons of tips, fresh bottles of water and breakfast.
The apartment is air conditioned and the bedroom can get a bit warmer but with 2 fans provided by Mercedes we slept very well.
Don't get fooled by the centra location the apartment is surprisingly quiet. Even with a party going on the plaza, the bedroom which is oriented towards the inner courtyard is completely silent.
We would definitely come again for the amazing value and great experience :)
