We loved our stay at Eric Vokel apartments. The apartment were very conveniently located for the metro or to walk to many of the tourist attractions. Malasaña is also a very interesting area with many nice restaurants and bars.
The staff in the apartments we're very helpful and helped to book a taxi to the airport and ensure we booked a taxi with a car seat for a toddler.
We would recommend anyone to stay here and would happily return some time.
