Most everything was great. Wonderful location with LOTS of local restaurants, bakery and butcher shop right downstairs, multiple small local groceries, etc.
Separate AC units for each bedroom and the living area.
Couple of thoughts - the balcony is tiny - I mean it runs along the length of the living area and around a partial corner to the area outside the master bedroom. In the pics, I kind of thought this would be deeper and more usable - it's essentially about a 2-foot wide ledge, just room to put a chair and tiny table for coffee outside or something. It isn't bad, I am pretty uncomfortable with heights, so even with the railing, I found it too off-putting to sit out there, it is pretty narrow.
The only problem we had with the place was the water in the master/en suite shower. This was mentioned in another review and I emailed to ask if both faucets were working or this had been addressed, etc., I think the previous review said the hot water wasn't working or something in one bathroom. I was told both hot and cold work fine. While this is true, there is a small eccentricity in the master shower - this is a 'blended' faucet where you have a handle you lift up and down for pressure/volume and swing left/right for hot/cold. The strange thing is, it works fine - but every 2-3 minutes or so, you can feel the water temp start to drop. In 6-8 seconds it will become pure cold, no matter if you swing the handle all the way to hot or not - in the full hot position, it will be pure cold. In 10-12 seconds it will swing back to your set temp (better get ready if you moved that handle to hot to try to compensate!). It's an odd scenario and I've tried to work out in my head how this could be happening. It is not like you get sudden shifts in water temp like in some homes when someone flushes a toilet and you instantly lose the cold portion of your water and your shower becomes scalding hot until that toilet tank fills back up and stops 'stealing' your cold supply, nor the alternate scenario when someone turns a tap on hot and you instantly get mostly cold coming through your showerhead until they turn it off. This is a slow swing, very predictable and strange, in my opinion. I shared it with Ana via WhatsApp and she said she would bring it to the attention of the owner. I really don't understand the etiology of this quirk, knowing how the internal valve works in these 'blending' type faucets. I wondered if it has something to do with the hot water heater itself - I'm not sure if this is an in-line electric heating element or what, I didn't see a hot water tank anywhere, and there is a switch in the hallway we were told to leave alone as it controls the hot water. If it's an in-line instant hot water element, I would suggest it is losing power every few minutes for a short stretch - overheating? Power conservation mode? I don't know. Overall it was a small thing and easily managed - my son said he thought it may have done it once in the hall bathroom, but it was consistent for both me and my wife in the en suite.
The apartment itself is great, location is great, overall we were extremely pleased and it has plenty of room. Communication was great. Taxi from El Prat airport was about 38Euros, I think, I would recommend this when you first arrive, as it will take a little bit to learn the subway system and hauling luggage up and down the stairs is rough - I'd say roughly 1/2 of the escalators we encountered in Barcelona were non-functional. And moreso the 'up' escalators for some reason? The 'down' escalators were more consistently functional, which seemed odd. Oh well.
Barcelona is an amazing city with a crazy amount of things to do, a zillion restaurants to try and fairly easy to get around once you learn how the subways and such work.
We would definitely stay in this place again and I can't recommend it highly enough!
