We were back in Barcelona for an extended stay and wanted to stay in an aparthotel. Sensation Sagrada Familia met all of our needs. Plenty of space to come back to after being out and about. The accommodations itself are modern, clean, and well appointed. While we love going out to eat, especially in Barcelona! It was nice to have a full kitchen. Location wise, this apartment is in a great location. Although it is only steps from the Sagrada Familia, you really get a quite neighborhood feel and don't necessarily feel like you are in a tourist trap. There are several restaurants, be weary of the Chinese owned ones serving "traditional Spanish fare", and look for authentic restaurants for the best food. One one block alone, there are about 3 or 4 grocery stores, and several more within a very short walk.
*It is rare to find coffee in room in Spanish hotels; this apartment had both an electric water heater (for tea or instant coffees) and a Nespresso (espresso pods sold at the front desk)
*The gym did the trick, but no free weights, only cardio equipment
*Laundry room is next to the gym, very useful
*If traveling around town by taxi, memorize the address, you'll have to give it to the driver, but no worries, Barcelona taxi drivers are among the best and know their city inside and out, you'll get dropped off right at the front door every time
*The WiFi was a little spotty during certain parts of the day. No rhyme or reason, it would just be extremely slow at times
Lastly, the staff is very warm, friendly, and inviting. Very helpful and accommodating.
