5 stars is not enough for this apartment. The location is amazing. Almost every day when it became too hot we were close enough to go back to the apartment, enjoy the air conditioning and have a beautiful coffee (thanks to the nespresso machine).
We were picked up at the airport (extra cost) and the driver had the key which meant there was no waiting around to access the apartment. It has a security entrance way so we always felt safe. The apartment is situated around bars and restaurants so can be a little bit noisier at the weekends, however, there are shutters on the windows which reduce the noise drastically.
The apartment is small but has everything you need. The thing I was most amazed at was that there were not only dishwasher tablets left there was also washing capsules for the washing machine. We have stayed in lots of apartments and this is the first one where there was enough cleaning products to ensure we could keep the place clean during our stay and not have to buy them once we arrive - thank you.
There is a folder in the apartment which gives lots of hints and tips of what to do and where to go around Lisbon which we found really helpful.
Some others asked about the air conditioning. There are 2 units - one in the main living area and one in the bedroom. They are very modern and very effective. They cooled the rooms down really quickly.
We really look forward to coming back to Lisbon some day and would hope to use the apartment again.
