We have an amazing journey in Barcelona, although we never meet Sofia, but she keep in touch with me and asked the feedbacks all the time. We are quite satisfied with the location of the apartment, it is very convenient for tourists to go to the metro station, u can take metro to the main tourists sites and monuments.
We also have some suggestions for the room:
1.the water heater is not stable, sometimes we take a shower by very hot water.
2.when we turn on the heating system, the room become stuffy, lack of fresh air.
3. the instruction is not clear enough, especially when we get lost in the small alleys.
located in the old town the surrounding quarter is not safe, take care of your pocket ,wallet and phone, don't come back late.
