We chose Alejandro and Fernando's place as not only did it look stylish the reviews were great! The apartment and hospitality lived up to expectations, the four of us were very comfortable; they both waited for us on the day of our arrival to let us into the apartment as we arrived late due to a flight delay- they were so flexible as to check-in time so this was vey convenient, Alejandro provided us with a welcome breakfast with enough milk, bread, jam, coffee/tea and some soft drinks to last a few days, the apartment had a nice and quiet balcony, comfy beds and was good to relax after a full days exploring, he also gave us a map and a guide for Barcelona to borrow as we came unprepared, he gave us some tips for the local area and booked a taxi for us back to the airport! He also recommended booking the Sagrada Famila which we did- it was worth it as there was 2hour queue so definitely do this!
The apartment itself is a 2-3 min walk from Urgell metro station or a 15 min walk to La Rambla so you get a chance to be close but not too close and about 30 mins to the beach which all in all is great. If you are going to use the metro I'd recommend getting your ticket the day you arrive to get value for money.
I would recommend trying to get/research some food recommendations before you come as the restaurants in the centre were ok but not great so try go a little off the beaten track- however we did stumble across a great tapas place called Bar Bitacora near Barcelonetta Metro Station on carre de Bilbao- does tapas which is both tasty and reasonable staff were friendly and gave us free shot of local sweet wine. Also make sure you go to La Boqueria a fresh food market so much good food there!
Glad we picked Alejandro and Fernando's place to explore this lovely city- will stay again on my next visit which I hope will be very soon! Thank-you!
