We spent a long Easter weekend in Nelson's apartment. He is an absolutely amazing and attentive host, making sure you have a comfortable stay and that you feel at ease with contacting him about any questions/recommendations etc. The flat itself is a perfect for a couple sharing and the location of it is absolutely in the heart of it all - and very close to transport links. There's also a handy supermarket a few minutes away. The reason for giving it 4 stars instead of 5 is that if you like a quiet apartment for your holiday (which we do), this might not be the best one to choose - for the first two nights we had some loud music from the apartment downstairs and you can also hear the people upstairs from you going about their business, as there is no soundproofing to speak of. There is also a fair bit of noise from the street outside, but this is to be expected. The bathroom is very snug, so if you are larger than the 'average person', you might also want to be aware of that. But I don't want to downplay the apartment too much, as it really is a wonderful, cosy place to stay while in Lisbon and Nelson has many things for you to recommend to see and do around town.
