Sérgio's apartment was exactly as advertised, and was a perfect base for our 4-day break. The bedrooms were very roomy with loads of storage space and the beds were very comfortable. The lounge was great for relaxing when it was a bit chilly, and when it was warmer the outdoor area was excellent for catching some evening sun and listening to the sound of the city. The kitchen had everything you'd need and was well set out.
Check-in was very smooth, and the real bonus was Sérgio's guide book which is incredibly detailed and makes touring the city that much easier. The location of the apartment was ideal for visiting various parts of the city.
Everything about the place was perfect and I highly recommend it.
